* shrink struct dentryNick Piggin2008-12-312-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iolock is dropped and re-acquired around the call to XFS_SEND_NAMESP(). 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Speculative allocation beyond eof doesn't work properly. It was broken some time ago after a code cleanup that moved what is now xfs_iomap_eof_align_last_fsb() and xfs_iomap_eof_want_preallocate() out of xfs_iomap_write_delay() into separate functions. 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 change fixes all the places that used to use the current file size. Reviewed-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The whole machinery to wait on I/O completion is related to the I/O path and should be there instead of in xfs_vnode.c. Also give the functions more descriptive names. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Niv Sardi <xaiki@sgi.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's just one caller of this helper, and it's much cleaner to just merge the xfs_do_force_shutdown call into it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's almost nothing left in this function, instead remove the IRELE on the real times inodes and the call to XFS_QM_UNMOUNT into xfs_unmountfs. For the regular unmount case that means it now also happenes after dmapi notification, but otherwise there is no difference in behaviour.

| * | | | no explicit xfs_iflush for special inodes during unmountChristoph Hellwig2008-12-045-106/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we explicitly call xfs_iflush on the quota, real-time and root inodes from xfs_unmount_flush. But we just called xfs_sync_inodes with SYNC_ATTR and do an XFS_bflush aka xfs_flush_buftarg to make sure all inodes are on disk already, so there is no need for these special cases.
