2008-08-13[XFS] remove some easy bhv_vnode_t instancesChristoph Hellwig
In various places we can just move a VFS_I call into the argument list of called functions/macros instead of having a local bhv_vnode_t. SGI-PV: 981498 SGI-Modid: xfs-linux-melb:xfs-kern:31776a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
2008-08-13[XFS] kill xfs_lock_dir_and_entryChristoph Hellwig
When multiple inodes are locked in XFS it happens in order of the inode number, with the everything but the first inode trylocked if any of the previous inodes is in the AIL. Except for the sorting of the inodes this logic is implemented in xfs_lock_inodes, but also partially duplicated in xfs_lock_dir_and_entry in a particularly stupid way adds a lock roundtrip if the inode ordering is not optimal. This patch adds a new helper xfs_lock_two_inodes that takes two inodes and locks them in the most optimal way according to the above locking protocol and uses it for all places that want to lock two inodes. The only caller of xfs_lock_inodes is xfs_rename which might lock up to four inodes.

2008-08-13[XFS] implement IHOLD/IRELE directlyChristoph Hellwig
Now that all direct calls to VN_HOLD/VN_RELE are gone we can implement IHOLD/IRELE directly. For the IHOLD case also replace igrab with a direct increment of i_count because we are guaranteed to already have a live and referenced inode by the VFS. Also remove the vn_hold statistic because it's been rather meaningless for some time with most references done by other callers.

2008-08-13[XFS] Use KM_NOFS for incore inode extent tree allocation V2David Chinner
If we allow incore extent tree allocations to recurse into the filesystem under memory pressure, new delayed allocations through xfs_iomap_write_delay() can deadlock on themselves if memory reclaim tries to write back dirty pages from that inode. It will deadlock in xfs_iomap_write_allocate() trying to take the ilock we already hold. This can also show up as complex ABBA deadlocks when multiple threads are triggering memory reclaim when trying to allocate extents. The main cause of this is the fact that delayed allocation is not done in a transaction, so KM_NOFS is not automatically added to the allocations to prevent this recursion. Mark all allocations done for the incore inode extent tree as KM_NOFS to ensure they never recurse back into the filesystem. Version 2: o KM_NOFS implies KM_SLEEP, so just use KM_NOFS SGI-PV: 981498 SGI-Modid: xfs-linux-melb:xfs-kern:31726a Signed-off-by: David Chinner <david@fromorbit.com> Signed-off-by: Niv Sardi <xaiki@sgi.com> Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>

2008-08-13[XFS] Avoid directly referencing the VFS inode.David Chinner
In several places we directly convert from the XFS inode to the linux (VFS) inode by a simple deference of ip->i_vnode. We should not do this - a helper function should be used to extract the VFS inode from the XFS inode. Introduce the function VFS_I() to extract the VFS inode from the XFS inode. The name was chosen to match XFS_I() which is used to extract the XFS inode from the VFS inode.

2008-08-12Make ioctl.h compatible with userlandMichael Abbott
The attached patch seems to already exist in a number of branches -- it keeps popping up on Google for me, and is certainly already in Debian -- but is strangely absent from mainstream. The problem appears to be that the patched file ends up as part of the target toolchain, but unfortunately the gcc constant folding doesn't appear to eliminate the __invalid_size_argument_for_IOC value early enough. Certainly compiling C++ programs which use _IO... macros as constants fails without this patch.

2008-08-12docsrc: build Documentation/ sourcesRandy Dunlap
Currently source files in the Documentation/ sub-dir can easily bit-rot since they are not generally buildable, either because they are hidden in text files or because there are no Makefile rules for them. This needs to be fixed so that the source files remain usable and good examples of code instead of bad examples. Add the ability to build source files that are in the Documentation/ dir. Add to Kconfig as "BUILD_DOCSRC" config symbol. Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the Documentation/ sources. Or enable BUILD_DOCSRC in the *config system. However, this symbol depends on HEADERS_CHECK since the header files need to be installed (for userspace builds).

2008-08-12seq_file: add seq_cpumask(), seq_nodemask()Alexey Dobriyan
Short enough reads from /proc/irq/*/smp_affinity return -EINVAL for no good reason. This became noticed with NR_CPUS=4096 patches, when length of printed representation of cpumask becase 1152, but cat(1) continued to read with 1024-byte chunks. bitmap_scnprintf() in good faith fills buffer, returns 1023, check returns -EINVAL. Fix it by switching to seq_file, so handler will just fill buffer and doesn't care about offsets, length, filling EOF and all this crap. For that add seq_bitmap(), and wrappers around it -- seq_cpumask() and seq_nodemask().

2008-08-12atmel_lcdfb: add board parameter specify framebuffer memory sizeHaavard Skinnemoen
Specify how much physically continuous, DMA capable memory will be allocated at driver initialization time. This allow to create framebuffer device with larger virtual resolution. Combine with y-panning this can be used to implement double buffering acceleration method.

2008-08-12atmel_lcdfb: set ypanstep to 1 and enable y-panning on AT91Haavard Skinnemoen
Panning in the y-direction can be done by simply changing the DMA base address. This code is already in place, but FBIOPAN_DISPLAY will currently fail because ypanstep is 0. Set ypanstep to 1 to indicate that we do support y-panning and also set the necessary acceleration flags on AT91 (AVR32 already have them.)
