| * include: linux/fs.h: put declarations in __KERNEL__Jan Engelhardt2009-01-011-9/+9
| | | | | | | | | | | | | | | | | | | | include/linux/fs.h contains externs for a bunch of variables. That obviously belongs under ifdef __KERNEL__.

| * shrink struct dentryNick Piggin2009-01-015-22/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct dentry is one of the most critical structures in the kernel. So it's sad to see it going neglected. With CONFIG_PROFILING turned on (which is probably the common case at least for distros and kernel developers), sizeof(struct dcache) == 208 here (64-bit). This gives 19 objects per slab. I packed d_mounted into a hole, and took another 4 bytes off the inline name length to take the padding out from the end of the structure. This shinks it to 200 bytes. I could have gone the other way and increased the length to 40, but I'm aiming for a magic number, read on... I then got rid of the d_cookie pointer. This shrinks it to 192 bytes. Rant: why was this ever a good idea? The cookie system should increase its hash size or use a tree or something if lookups are a problem. Also the "fast dcookie lookups" in oprofile should be moved into the dcookie code -- how can oprofile possibly care about the dcookie_mutex? It gets dropped after get_dcookie() returns so it can't be providing any sort of protection. At 192 bytes, 21 objects fit into a 4K page, saving about 3MB on my system with ~140 000 entries allocated. 192 is also a multiple of 64, so we get nice cacheline alignment on 64 and 32 byte line systems -- any given dentry will now require 3 cachelines to touch all fields wheras previously it would require 4. I know the inline name size was chosen quite carefully, however with the reduction in cacheline footprint, it should actually be just about as fast to do a name lookup for a 36 character name as it was before the patch (and faster for other sizes). The memory footprint savings for names which are <= 32 or > 36 bytes long should more than make up for the memory cost for 33-36 byte names. Performance is a feature...

| * fs: reorder struct inotify_device on 64bits to remove paddingRichard Kennedy2009-01-011-1/+1

While the iolock is released the file can become cached. We then 'goto retry' and - if we are doing direct I/O - mapping->nrpages may now be non zero but need_i_mutex will be zero and we will hit the WARN_ON(). Since we have dropped the I/O lock then the file size may have also changed so what we need to do here is 'goto start' like we do for the XFS_SEND_DATA() DMAPI event. We also need to update the filesize before releasing the iolock so that needs to be done before the XFS_SEND_NAMESP event. If we drop the iolock before setting the filesize we could race with a truncate. Reviewed-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>

The code used to use the current file size in various checks but got changed to be max(file_size, i_new_size). Since i_new_size is the result of 'offset + count' then in xfs_iomap_eof_want_preallocate() the check for '(offset + count) <= isize' will always be true. ie if 'offset + count' is > ip->i_size then isize will be i_new_size and equal to 'offset + count'.

This is because xfs_iget_cache_hit() first clears XFS_IRECLAIMABLE and then calls __xfs_inode_clear_reclaim_tag() while only holding the pag_ici_lock in read mode so we can race with xfs_reclaim_inodes_ag(). Looks like xfs_reclaim_inodes_ag() will do the right thing anyway so just remove the assert. Thanks to Christoph for pointing out where the problem was.

This requires a check to be made after all the inodes involved in the rename are locked. We fail to unlock the inodes correctly if we disallow the rename when the target is outside the current directory tree. This results in a hang on the next access to the inodes involved in failed rename.
