2008-05-23[XFS] Fix fsync() b0rkage.David Chinner
xfs_fsync() fails to wait for data I/O completion before checking if the inode is dirty or clean to decide whether to log the inode or not. This misses inode size updates when the data flushed by the fsync() is extending the file. Hence, like fdatasync(), we need to wait for I/o completion first, then check the inode for cleanliness. Doing so makes the behaviour of xfs_fsync() identical for fsync and fdatasync and we *always* use synchronous semantics if the inode is dirty. Therefore also kill the differences and remove the unused flags from the xfs_fsync function and callers.

2008-04-18[XFS] kill xfs_get_dir_entryChristoph Hellwig
Instead of of xfs_get_dir_entry use a macro to get the xfs_inode from the dentry in the callers and grab the reference manually. Only grab the reference once as it's fine to keep it over the dmapi calls. (And even that reference is actually superflous in Linux but I'll leave that for another patch) SGI-PV: 976035 SGI-Modid: xfs-linux-melb:xfs-kern:30531a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
2008-04-18[XFS] Don't block pdflush when writing back inodesDavid Chinner
When pdflush is writing back inodes, it can get stuck on inode cluster buffers that are currently under I/O. This occurs when we write data to multiple inodes in the same inode cluster at the same time. Effectively, delayed allocation marks the inode dirty during the data writeback. Hence if the inode cluster was flushed during the writeback of the first inode, the writeback of the second inode will block waiting for the inode cluster write to complete before writing it again for the newly dirtied inode. Basically, we want to avoid this from happening so we don't block pdflush and slow down all of writeback. Hence we introduce a non-blocking async inode flush flag that pdflush uses. If this flag is set, we use non-blocking operations (e.g. try locks) whereever we can to avoid blocking or extra I/O being issued.

2007-10-15[XFS] use filldir internallyChristoph Hellwig
Currently xfs has a rather complicated internal scheme to allow for different directory formats in IRIX. This patch rips all code related to this out and pushes useage of the Linux filldir callback into the lowlevel directory code. This does not make the code any less portable because filldir can be used to create dirents of all possible variations (including the IRIX ones as proved by the IRIX binary emulation code under arch/mips/). This patch get rid of an unessecary copy in the readdir path, about 400 lines of code and one of the last two users of the uio structure. This version is updated to deal with dmapi aswell which greatly simplifies the get_dirattrs code. The dmapi part has been tested using the get_dirattrs tools from the xfstest dmapi suite1 with various small and large directories.

2007-07-14[XFS] XFS should not be looking at filp reference countsChristoph Hellwig
A check for file_count is always a bad idea. Linux has the ->release method to deal with cleanups on last close and ->flush is only for the very rare case where we want to perform an operation on every drop of a reference to a file struct. This patch gets rid of vop_close and surrounding code in favour of simply doing the page flushing from ->release.

2007-02-10[XFS] Keep stack usage down for 4k stacks by using noinline.David Chinner
gcc-4.1 and more recent aggressively inline static functions which increases XFS stack usage by ~15% in critical paths. Prevent this from occurring by adding noinline to the STATIC definition. Also uninline some functions that are too large to be inlined and were causing problems with CONFIG_FORCED_INLINING=y. Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.
