2007-04-24Taskstats fix the structure members alignment issueBalbir Singh
We broke the the alignment of members of taskstats to the 8 byte boundary with the CSA patches. In the current kernel, the taskstats structure is not suitable for use by 32 bit applications in a 64 bit kernel. On x86_64 Offsets of taskstats' members (64 bit kernel, 64 bit application) @taskstats'offsetof[@taskstats'indices] = ( 0, # version 4, # ac_exitcode 8, # ac_flag 9, # ac_nice 16, # cpu_count 24, # cpu_delay_total 32, # blkio_count 40, # blkio_delay_total 48, # swapin_count 56, # swapin_delay_total 64, # cpu_run_real_total 72, # cpu_run_virtual_total 80, # ac_comm 112, # ac_sched 113, # ac_pad 116, # ac_uid 120, # ac_gid 124, # ac_pid 128, # ac_ppid 132, # ac_btime 136, # ac_etime 144, # ac_utime 152, # ac_stime 160, # ac_minflt 168, # ac_majflt 176, # coremem 184, # virtmem 192, # hiwater_rss 200, # hiwater_vm 208, # read_char 216, # write_char 224, # read_syscalls 232, # write_syscalls 240, # read_bytes 248, # write_bytes 256, # cancelled_write_bytes ); Offsets of taskstats' members (64 bit kernel, 32 bit application) @taskstats'offsetof[@taskstats'indices] = ( 0, # version 4, # ac_exitcode 8, # ac_flag 9, # ac_nice 12, # cpu_count 20, # cpu_delay_total 28, # blkio_count 36, # blkio_delay_total 44, # swapin_count 52, # swapin_delay_total 60, # cpu_run_real_total 68, # cpu_run_virtual_total 76, # ac_comm 108, # ac_sched 109, # ac_pad 112, # ac_uid 116, # ac_gid 120, # ac_pid 124, # ac_ppid 128, # ac_btime 132, # ac_etime 140, # ac_utime 148, # ac_stime 156, # ac_minflt 164, # ac_majflt 172, # coremem 180, # virtmem 188, # hiwater_rss 196, # hiwater_vm 204, # read_char 212, # write_char 220, # read_syscalls 228, # write_syscalls 236, # read_bytes 244, # write_bytes 252, # cancelled_write_bytes ); This is one way to solve the problem without re-arranging structure members is to pack the structure. The patch adds an __attribute__((aligned(8))) to the taskstats structure members so that 32 bit applications using taskstats can work with a 64 bit kernel. Using __attribute__((packed)) would break the 64 bit alignment of members. The fix was tested on x86_64. After the fix, we got Offsets of taskstats' members (64 bit kernel, 64 bit application) @taskstats'offsetof[@taskstats'indices] = ( 0, # version 4, # ac_exitcode 8, # ac_flag 9, # ac_nice 16, # cpu_count 24, # cpu_delay_total 32, # blkio_count 40, # blkio_delay_total 48, # swapin_count 56, # swapin_delay_total 64, # cpu_run_real_total 72, # cpu_run_virtual_total 80, # ac_comm 112, # ac_sched 113, # ac_pad 120, # ac_uid 124, # ac_gid 128, # ac_pid 132, # ac_ppid 136, # ac_btime 144, # ac_etime 152, # ac_utime 160, # ac_stime 168, # ac_minflt 176, # ac_majflt 184, # coremem 192, # virtmem 200, # hiwater_rss 208, # hiwater_vm 216, # read_char 224, # write_char 232, # read_syscalls 240, # write_syscalls 248, # read_bytes 256, # write_bytes 264, # cancelled_write_bytes ); Offsets of taskstats' members (64 bit kernel, 32 bit application) @taskstats'offsetof[@taskstats'indices] = ( 0, # version 4, # ac_exitcode 8, # ac_flag 9, # ac_nice 16, # cpu_count 24, # cpu_delay_total 32, # blkio_count 40, # blkio_delay_total 48, # swapin_count 56, # swapin_delay_total 64, # cpu_run_real_total 72, # cpu_run_virtual_total 80, # ac_comm 112, # ac_sched 113, # ac_pad 120, # ac_uid 124, # ac_gid 128, # ac_pid 132, # ac_ppid 136, # ac_btime 144, # ac_etime 152, # ac_utime 160, # ac_stime 168, # ac_minflt 176, # ac_majflt 184, # coremem 192, # virtmem 200, # hiwater_rss 208, # hiwater_vm 216, # read_char 224, # write_char 232, # read_syscalls 240, # write_syscalls 248, # read_bytes 256, # write_bytes 264, # cancelled_write_bytes ); Signed-off-by: Balbir Singh <balbir@linux.vnet.ibm.com> Cc: Jay Lan <jlan@engr.sgi.com> Cc: Shailabh Nagar <nagar@watson.ibm.com> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-04-14NFS: Ensure PG_writeback is cleared when writeback failsTrond Myklebust
If the writebacks are cancelled via nfs_cancel_dirty_list, or due to the memory allocation failing in nfs_flush_one/nfs_flush_multi, then we must ensure that the PG_writeback flag is cleared. Also ensure that we actually own the PG_writeback flag whenever we schedule a new writeback by making nfs_set_page_writeback() return the value of test_set_page_writeback(). The PG_writeback page flag ends up replacing the functionality of the PG_FLUSHING nfs_page flag, so we rip that out too.

2007-04-10ide: correctly prevent IDE timer expiry function to run if request was ↵Suleiman Souhlal
already handled It is possible for the timer expiry function to run even though the request has already been handled: ide_timer_expiry() only checks that the handler is not NULL, but it is possible that we have handled a request (thus clearing the handler) and then started a new request (thus starting the timer again, and setting a handler). A simple way to exhibit this is to set the DMA timeout to 1 jiffy and run dd: The kernel will panic after a few minutes because ide_timer_expiry() tries to add a timer when it's already active. To fix this, we simply add a request generation count that gets incremented at every interrupt, and check in ide_timer_expiry() that we have not already handled a new interrupt before running the expiry function.

2007-04-04[PATCH] remove protection of LANANA-reserved majorsAndrew Morton
Revert all this. It can cause device-mapper to receive a different major from earlier kernels and it turns out that the Amanda backup program (via GNU tar, apparently) checks major numbers on files when performing incremental backups. Which is a bit broken of Amanda (or tar), but this feature isn't important enough to justify the churn.

2007-04-02[PATCH] Fix microcode-related suspend problemRafael J. Wysocki
Fix the regression resulting from the recent change of suspend code ordering that causes systems based on Intel x86 CPUs using the microcode driver to hang during the resume. The problem occurs since the microcode driver uses request_firmware() in its CPU hotplug notifier, which is called after tasks has been frozen and hangs. It can be fixed by telling the microcode driver to use the microcode stored in memory during the resume instead of trying to load it from disk. Signed-off-by: Rafael J.

2007-03-26ide: use correct IDE error recoverySuleiman Souhlal
IDE error recovery is using IDLE IMMEDIATE if the drive is busy or has DRQ set. This violates the ATA spec (can only send IDLE IMMEDIATE when drive is not busy) and really hoses up some drives (modern drives will not be able to recover using this error handling). The correct thing to do is issue a SRST followed by a SET FEATURES command. This is what Western Digital recommends for error recovery and what Western Digital says Windows does.  It also does not violate the ATA spec as far as I can tell. Bart: * port the patch over the current tree * undo the recalibration code removal * send SET FEATURES command after checking for good drive status * don't check whether the current request is of REQ_TYPE_ATA_{CMD,TASK} type because we need to send SET FEATURES before handling any requests * some pre-ATA4 drives require INITIALIZE DEVICE PARAMETERS command before other commands (except IDENTIFY) so send SET FEATURES only if there are no pending drive->special requests * update comments and patch description * any bugs introduced by this patch are mine and not Suleiman's :-) Signed-off-by: Suleiman Souhlal <suleiman@google.com> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

The current NFS client congestion logic is severly broken, it marks the backing device congested during each nfs_writepages() call but doesn't mirror this in nfs_writepage() which makes for deadlocks. Also it implements its own waitqueue. Replace this by a more regular congestion implementation that puts a cap on the number of active writeback pages and uses the bdi congestion waitqueue. Also always use an interruptible wait since it makes sense to be able to SIGKILL the process even for mounts without 'intr'.

2007-03-16[PATCH] spi: destroy workqueue after spi_unregister_masterChris Lesiak
Fix a bug in the cleanup of an spi_bitbang bus. The workqueue associated with the bus was destroyed before the call to spi_unregister_master. That meant that spi devices on that bus would be unable to do IO in their remove method. The shutdown flag should have been able to prevent a segfault, but was never getting set. By waiting to destroy the workqueue until after the master is unregistered, devices are able to do IO in their remove methods. An added benefit is that neither the shutdown flag nor a wait for the queue of messages to empty is needed.

2007-03-16[PATCH] ufs2: more correct work with timeEvgeniy Dushistov
This patch corrects work with time in UFS2 case. 1) According to UFS2 disk layout modification/access and so on "time" should be hold in two variables one 64bit for seconds and another 32bit for nanoseconds, at now for some unknown reason we suppose that "inode time" holds in three variables 32bit for seconds, 32bit for milliseconds and 32bit for nanoseconds. 2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of getting values from "on disk inode"(this should close http://bugzilla.kernel.org/show_bug.cgi?id=7991).

2007-03-15[PATCH] sysfs and driver core: add callback helper, used by SCSI and S390Alan Stern
This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.

2007-03-12[PATCH] pci: Repair pci_save/restore_state so we can restore one save many ↵Eric W. Biederman
times. Because we do not reserve space for the pci-x and pci-e state in struct pci dev we need to dynamically allocate it. However because we need to support restore being called multiple times after a single save it is never safe to free the buffers we have allocated to hold the state. So this patch modifies the save routines to first check to see if we have already allocated a state buffer before allocating a new one. Then the restore routines are modified to not free the state after restoring it. Simple and it fixes some subtle error path handling bugs, that are hard to test for. Signed-off-by: Eric W.

2007-03-12[PATCH] msi: Safer state caching.Eric W. Biederman
There are two ways pci_save_state and pci_restore_state are used. As helper functions during suspend/resume, and as helper functions around a hardware reset event. When used as helper functions around a hardware reset event there is no reason to believe the calls will be paired, nor is there a good reason to believe that if we restore the msi state from before the reset that it will match the current msi state. Since arch code may change the msi message without going through the driver, drivers currently do not have enough information to even know when to call pci_save_state to ensure they will have msi state in sync with the other kernel irq reception data structures. It turns out the solution is straight forward, cache the state in the existing msi data structures (not the magic pci saved things) and have the msi code update the cached state each time we write to the hardware. This means we never need to read the hardware to figure out what the hardware state should be. By modifying the caching in this manner we get to remove our save_state routines and only need to provide restore_state routines. The only fields that were at all tricky to regenerate were the msi and msi-x control registers and the way we regenerate them currently is a bit dependent upon assumptions on how we use the allow msi registers to be configured and used making the code a little bit brittle. If we ever change what cases we allow or how we configure the msi bits we can address the fragility then. Signed-off-by: Eric W.

2007-03-08[PATCH] Add epoll compat_ code to fs/compat.cDavide Libenzi
IA64 and ARM-OABI are currently using their own version of epoll compat_ code. An architecture needs epoll_event translation if alignof(u64) in 32 bit mode is different from alignof(u64) in 64 bit mode. If an architecture needs epoll_event translation, it must define struct compat_epoll_event in asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use compat_sys_epoll_ctl and compat_sys_epoll_wait. All 64 bit architecture should use compat_sys_epoll_pwait.
