In xfs_write() the iolock is dropped and reacquired in XFS_SEND_DATA() which means that the file could change from not-cached to cached and we need to redo the direct I/O checks. We should also redo the direct I/O checks when the file size changes regardless if O_APPEND is set or not.

The problem that has been addressed is that of synchronising updates of the file size with writes that extend a file. Without the fix the update of a file's size, as a result of a write beyond eof, is independent of when the cached data is flushed to disk. Often the file size update would be written to the filesystem log before the data is flushed to disk. When a system crashes between these two events and the filesystem log is replayed on mount the file's size will be set but since the contents never made it to disk the file is full of holes. If some of the cached data was flushed to disk then it may just be a section of the file at the end that has holes. There are existing fixes to help alleviate this problem, particularly in the case where a file has been truncated, that force cached data to be flushed to disk when the file is closed. If the system crashes while the file(s) are still open then this flushing will never occur. The fix that we have implemented is to introduce a second file size, called the in-memory file size, that represents the current file size as viewed by the user. The existing file size, called the on-disk file size, is the one that get's written to the filesystem log and we only update it when it is safe to do so. When we write to a file beyond eof we only update the in- memory file size in the write operation. Later when the I/O operation, that flushes the cached data to disk completes, an I/O completion routine will update the on-disk file size. The on-disk file size will be updated to the maximum offset of the I/O or to the value of the in-memory file size if the I/O includes eof.

This change addresses a race in xfs_write() where, for direct I/O, the flags need_i_mutex and need_flush are setup before the iolock is acquired. The logic used to setup the flags may change between setting the flags and acquiring the iolock resulting in these flags having incorrect values. For example, if a file is not currently cached then need_i_mutex is set to zero and then if the file is cached before the iolock is acquired we will fail to do the flushinval before the direct write. The flush (and also the call to xfs_zero_eof()) need to be done with the iolock held exclusive so we need to acquire the iolock before checking for cached data (or if the write begins after eof) to prevent this state from changing. For direct I/O I've chosen to always acquire the iolock in shared mode initially and if there is a need to promote it then drop it and reacquire it. There's also some other tidy-ups including removing the O_APPEND offset adjustment since that work is done in generic_write_checks() (and we don't use offset as an input parameter anywhere).

This patch handles error return values in fs_flush_pages and fs_flushinval_pages. It changes the prototype of fs_flushinval_pages so we can propogate the errors and handle them at higher layers. I also modified xfs_itruncate_start so that it could propogate the error further.

xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has. If this functionality ever goes into Linux, it will be provided at a different layer, most likely through the security hooks in the kernel so we will never need this functionality in XFS.

The problem is the two callers of xfs_iozero() are rounding out the range to be zeroed to the end of a fsb and in some cases this extends past the new eof. The call to commit_write() in xfs_iozero() will cause the Linux inode's file size to be set too high.

This patch cleans up generic_file_*_read/write() interfaces. Christoph Hellwig gave me the idea for this clean ups. In a nutshell, all filesystems should set .aio_read/.aio_write methods and use do_sync_read/ do_sync_write() as their .read/.write methods. This allows us to cleanup all variants of generic_file_* routines. Final available interfaces: generic_file_aio_read() - read handler generic_file_aio_write() - write handler generic_file_aio_write_nolock() - no lock write handler __generic_file_aio_write_nolock() - internal worker routine Signed-off-by: NBadari Pulavarty <pbadari@us.ibm.com> Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

To allow various options to work per-mount instead of per-sb we need a struct vfsmount when updating ctime and mtime. This preparation patch replaces the inode_update_time routine with a file_update_atime routine so we can easily get at the vfsmount. (and the file makes more sense in this context anyway). Also get rid of the unused second argument - we always want to update the ctime when calling this routine.
