      xfs: remove the i_size field in struct xfs_inode · ce7ae151
      Christoph Hellwig authored
      
      
      There is no fundamental need to keep an in-memory inode size copy in the XFS
      inode.  We already have the on-disk value in the dinode, and the separate
      in-memory copy that we need for regular files only in the XFS inode.
      
      Remove the xfs_inode i_size field and change the XFS_ISIZE macro to use the
      VFS inode i_size field for regular files.  Switch code that was directly
      accessing the i_size field in the xfs_inode to XFS_ISIZE, or in cases where
      we are limited to regular files direct access of the VFS inode i_size field.
      
      This also allows dropping some fairly complicated code in the write path
      which dealt with keeping the xfs_inode i_size uptodate with the VFS i_size
      that is getting updated inside ->write_end.
      
      Note that we do not bother resetting the VFS i_size when truncating a file
      that gets freed to zero as there is no point in doing so because the VFS inode
      is no longer in use at this point.  Just relax the assert in xfs_ifree to
      only check the on-disk size instead.

      xfs: remove xfs_itruncate_data · 673e8e59
      Christoph Hellwig authored
      
      
      This wrapper isn't overly useful, not to say rather confusing.
      
      Around the call to xfs_itruncate_extents it does:
      
       - add tracing
       - add a few asserts in debug builds
       - conditionally update the inode size in two places
       - log the inode
      
      Both the tracing and the inode logging can be moved to xfs_itruncate_extents
      as they are useful for the attribute fork as well - in fact the attr code
      already does an equivalent xfs_trans_log_inode call just after calling
      xfs_itruncate_extents.  The conditional size updates are a mess, and there
      was no reason to do them in two places anyway, as the first one was
      conditional on the inode having extents - but without extents we
      xfs_itruncate_extents would be a no-op and the placement wouldn't matter
      anyway.  Instead move the size assignments and the asserts that make sense
      to the callers that want it.
      
      As a side effect of this clean up xfs_setattr_size by introducing variables
      for the old and new inode size, and moving the size updates into a common
      place.

      xfs: simplify xfs_trans_ijoin* again · ddc3415a
      Christoph Hellwig authored
      
      
      There is no reason to keep a reference to the inode even if we unlock
      it during transaction commit because we never drop a reference between
      the ijoin and commit.  Also use this fact to merge xfs_trans_ijoin_ref
      back into xfs_trans_ijoin - the third argument decides if an unlock
      is needed now.
      
      I'm actually starting to wonder if allowing inodes to be unlocked
      at transaction commit really is worth the effort.  The only real
      benefit is that they can be unlocked earlier when commiting a
      synchronous transactions, but that could be solved by doing the
      log force manually after the unlock, too.

      xfs: remove subdirectories · c59d87c4

      Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the
      annoying subdirectories in the XFS source code.  Besides the large
      amount of file rename the only changes are to the Makefile, a few
      files including headers with the subdirectory prefix, and the binary
      sysctl compat code that includes a header under fs/xfs/ from
      kernel/.

      xfs: split xfs_itruncate_finish · 8f04c47a
      Christoph Hellwig authored
      
      
      Split the guts of xfs_itruncate_finish that loop over the existing extents
      and calls xfs_bunmapi on them into a new helper, xfs_itruncate_externs.
      Make xfs_attr_inactive call it directly instead of xfs_itruncate_finish,
      which allows to simplify the latter a lot, by only letting it deal with
      the data fork.  As a result xfs_itruncate_finish is renamed to
      xfs_itruncate_data to make its use case more obvious.
      
      Also remove the sync parameter from xfs_itruncate_data, which has been
      unessecary since the introduction of the busy extent list in 2002, and
      completely dead code since 2003 when the XFS_BMAPI_ASYNC parameter was
      made a no-op.
      
      I can't actually see why the xfs_attr_inactive needs to set the transaction
      sync, but let's keep this patch simple and without changes in behaviour.
      
      Also avoid passing a useless argument to xfs_isize_check, and make it
      private to xfs_inode.c.

      xfs: Extend project quotas to support 32bit project ids · 6743099c
      Arkadiusz Mi?kiewicz authored
      
      
      This patch adds support for 32bit project quota identifiers.
      
      On disk format is backward compatible with 16bit projid numbers. projid
      on disk is now kept in two 16bit values - di_projid_lo (which holds the
      same position as old 16bit projid value) and new di_projid_hi (takes
      existing padding) and converts from/to 32bit value on the fly.
      
      xfs_admin (for existing fs), mkfs.xfs (for new fs) needs to be used
      to enable PROJID32BIT support.

      xfs: split out inode walk inode grabbing · e13de955
      Dave Chinner authored
      
      
      When doing read side inode cache walks, the code to validate and
      grab an inode is common to all callers. Split it out of the execute
      callbacks in preparation for batching lookups. Similarly, split out
      the inode reference dropping from the execute callbacks into the
      main lookup look to be symmetric with the grab.

      xfs: don't use vfs writeback for pure metadata modifications · dcd79a14
      Dave Chinner authored
      
      
      Under heavy multi-way parallel create workloads, the VFS struggles
      to write back all the inodes that have been changed in age order.
      The bdi flusher thread becomes CPU bound, spending 85% of it's time
      in the VFS code, mostly traversing the superblock dirty inode list
      to separate dirty inodes old enough to flush.
      
      We already keep an index of all metadata changes in age order - in
      the AIL - and continued log pressure will do age ordered writeback
      without any extra overhead at all. If there is no pressure on the
      log, the xfssyncd will periodically write back metadata in ascending
      disk address offset order so will be very efficient.
      
      Hence we can stop marking VFS inodes dirty during transaction commit
      or when changing timestamps during transactions. This will keep the
      inodes in the superblock dirty list to those containing data or
      unlogged metadata changes.
      
      However, the timstamp changes are slightly more complex than this -
      there are a couple of places that do unlogged updates of the
      timestamps, and the VFS need to be informed of these. Hence add a
      new function xfs_trans_ichgtime() for transactional changes,
      and leave xfs_ichgtime() for the non-transactional changes.

      xfs: add a shrinker to background inode reclaim · 9bf729c0
      Dave Chinner authored
      
      
      On low memory boxes or those with highmem, kernel can OOM before the
      background reclaims inodes via xfssyncd. Add a shrinker to run inode
      reclaim so that it inode reclaim is expedited when memory is low.
      
      This is more complex than it needs to be because the VM folk don't
      want a context added to the shrinker infrastructure. Hence we need
      to add a global list of XFS mount structures so the shrinker can
      traverse them.

      xfs: event tracing support · 0b1b213f
      Christoph Hellwig authored
      Convert the old xfs tracing support that could only be used with the
      out of tree kdb and xfsidbg patches to use the generic event tracer.
      
      To use it make sure CONFIG_EVENT_TRACING is enabled and then enable
      all xfs trace channels by:
      
         echo 1 > /sys/kernel/debug/tracing/events/xfs/enable
      
      or alternatively enable single events by just doing the same in one
      event subdirectory, e.g.
      
         echo 1 > /sys/kernel/debug/tracing/events/xfs/xfs_ihold/enable
      
      or set more complex filters, etc. In Documentation/trace/events.txt
      all this is desctribed in more detail.  To reads the events do a
      
         cat /sys/kernel/debug/tracing/trace
      
      Compared to the last posting this patch converts the tracing mostly to
      the one tracepoint per callsite model that other users of the new
      tracing facility also employ.  This allows a very fine-grained control
      of the tracing, a cleaner output of the traces and also enables the
      perf tool to use each tracepoint as a virtual performance counter,
           allowing us to e.g. count how often certain workloads git various
           spots in XFS.  Take a look at
      
          http://lwn.net/Articles/346470/
      
      
      
      for some examples.
      
      Also the btree tracing isn't included at all yet, as it will require
      additional core tracing features not in mainline yet, I plan to
      deliver it later.
      
      And the really nice thing about this patch is that it actually removes
      many lines of code while adding this nice functionality:
