2009-09-11[S390] tape: Use pr_xxx instead of dev_xxx in shared driver codeMichael Holzheu
For messages from the tape core that is shared between the 3590 and 34xx tape disciplines, we want to have the "tape" prefix instead of "tape_3590" or "tape_34xx". In order to fix this, we now use the pr_xxx printk macros. Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2009-09-11[S390] tape: Fix device online messagesMichael Holzheu
Currently, when a tape device is set online and no cartridge is loaded, we get the messages "The tape cartridge has been successfully unloaded" and "Determining the size of the recorded area". These messages are not correct. To fix this, we now print the "cartridge loaded/unloaded" messages only, when the load/unload event really occurs. In addition to that, the message "Determining the size of the recorded area" is only printed, if a cartridge is loaded.

2009-09-11[S390] vmur: Invalid allocation sequence for vmur classMichael Holzheu
The vmur class is allocated after the CCW driver is registered and it is destroyed before the CCW driver is unregistered. This is not the correct sequence, because the vmur class can be used via driver core callbacks that are triggered during the CCW driver deregistration. For Example: 1. vmur device is online 2. vmur module is unloaded This leads to the following function call stack: <4> [<0000000000387286>] device_destroy+0x36/0x5c <4> [<000003e000209714>] ur_set_offline_force+0x9c/0x10c [vmur] <4> [<000003e00020a928>] ur_remove+0x64/0xbc [vmur] <4> [<00000000003e4d2e>] ccw_device_remove+0x42/0x1ac <4> [<000000000038a1aa>] __device_release_driver+0x9a/0xe4 <4> [<000000000038a2da>] driver_detach+0xe6/0xec <4> [<0000000000388ee4>] bus_remove_driver+0xc0/0x108 <4> [<000003e00020ad5a>] ur_exit+0x52/0x84 [vmur] In device_destroy() the vmur class is used. Since it is already freed, this can lead to a kernel panic. To fix the problem, the vmur class has to be allocated before the CCW driver is registered and destroyed after the CCW driver has ben unregistered.

2009-06-22[S390] Use del_timer instead of del_timer_syncMichael Holzheu
When syncing the sclp console queue, we call del_timer_sync() while holding the "sclp_con_lock" spinlock. This lock is also taken in the timer function "sclp_console_timeout". Therefore the sync version of del_timer() cannot be used here. Because the synchronous deletion of the timer is only needed in the suspend callback and in that case only one CPU is remaining and therefore it is not possible that the timer function is running in parallel, we can safely use del_timer() instead of del_timer_sync().

2009-06-16[S390] pm: con3270 power management callbacks.Martin Schwidefsky
Introduce the power management callbacks to the 3270 driver. On suspend the current 3270 view is deactivated and for non-console 3270 device the release callback is done. This disconnects the current tty / fullscreen application from the 3270 device. On resume the current view is reactivated, on the tty you get a fresh login. If the system panics before the 3270 device has been resumed, the ccw device for the 3270 console is reactivated with ccw_device_force_console.

2009-06-16[S390] pm: power management support for SCLP drivers.Michael Holzheu
The SCLP base driver defines a new notifier call back for all upper level SCLP drivers, like the SCLP console, etc. This guarantees that in suspend first the upper level drivers are suspended and afterwards the SCLP base driver. For resume it is the other way round. The SCLP base driver itself registers a new platform device at the platform bus and gets PM notifications via the dev_pm_ops. In suspend, the SCLP base driver switches off the receiver and sender mask This is done in sclp_deactivate(). After suspend all new requests will be rejected with -EIO and no more interrupts will be received, because the masks are switched off. For resume the sender and receiver masks are reset in the sclp_reactivate() function. When the SCLP console is suspended, all new messages are cached in the sclp console buffers. In resume, all the cached messages are written to the console. In addition to that we have an early resume function that removes the cached messages from the suspend image.

2009-06-16[S390] pm: vmwatchdog power management callbacks.Christian Borntraeger
This patch implements suspend/hibernation for the vmwatchdog driver. The pm_notifier_callchain is used to get control on PM events. Since watchdog operation and suspend cannot work together in a reliable fashion, the open flag is also used to prevent suspend and open from happening at the same time. The watchdog can also be active with no open file descriptor. This patch adds another flag which is only changed in vmwdt_keep_alive and vmwdt_disable.

2009-06-16[S390] pm: con3215 power management callbacksMartin Schwidefsky
Introduce the power management callbacks to the 3215 console. On suspend the console buffer is flushed to the 3215 device to have an empty console buffer. Printks done while the 3215 device is suspended are buffered in the 64K buffer of the 3215 device. If the buffer is full new messages will push out the oldest messages to make room for the most recent message. On resume the buffered messages are printed. If the system panics before the 3215 device is resumed ccw_device_force_console is used to get the console working again. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-15s390: remove driver_data direct access of struct deviceGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

2009-06-12[S390] 3270: lock dependency fixesMartin Schwidefsky
Lockdep found a problem with the lock order of the view lock and the ccw device lock. raw3270_activate_view/raw3270_deactivate_view first take the ccw device lock then call the activate/deactivate functions of the view which take view lock. The update functions of the con3270/tty3270 view will first take the view lock, then take the ccw device lock. To fix this the activate/deactivate functions are changed to avoid taking the view lock by moving the functions calls that modify the 3270 output buffer to the update function which is called by a timer.

2009-05-22block: Do away with the notion of hardsect_sizeMartin K. Petersen
Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: Martin K.

2009-05-11block: implement and enforce request peek/start/fetchTejun Heo
Till now block layer allowed two separate modes of request execution. A request is always acquired from the request queue via elv_next_request(). After that, drivers are free to either dequeue it or process it without dequeueing. Dequeue allows elv_next_request() to return the next request so that multiple requests can be in flight. Executing requests without dequeueing has its merits mostly in allowing drivers for simpler devices which can't do sg to deal with segments only without considering request boundary. However, the benefit this brings is dubious and declining while the cost of the API ambiguity is increasing. Segment based drivers are usually for very old or limited devices and as converting to dequeueing model isn't difficult, it doesn't justify the API overhead it puts on block layer and its more modern users. Previous patches converted all block low level drivers to dequeueing model. This patch completes the API transition by... * renaming elv_next_request() to blk_peek_request() * renaming blkdev_dequeue_request() to blk_start_request() * adding blk_fetch_request() which is combination of peek and start * disallowing completion of queued (not started) requests * applying new API to all LLDs Renamings are for consistency and to break out of tree code so that it's apparent that out of tree drivers need updating.

When I review ocfs2 code, find there are 2 typos to "successfull". After doing grep "successfull " in kernel tree, 22 typos found totally -- great minds always think alike :) This patch fixes all the similar typos. Thanks for Randy's ack and comments.
