      GFS2: Fix lseek after SEEK_DATA, SEEK_HOLE have been added · 9453615a
      Steven Whitehouse 提交于
      We need to take the inode's glock whenever the inode's size
      is referenced, otherwise it might not be uptodate. Even
      though generic_file_llseek_unlocked() doesn't implement
      SEEK_DATA, SEEK_HOLE directly, it does reference the inode's
      size in those cases, so we need to add them to the list
      of origins which need the glock.

      GFS2: Clean up gfs2_create · 9a63edd1
      Steven Whitehouse 提交于
      If we pass through knowledge of whether the creation is intended to be
      exclusive or not, then we can deal with that in gfs2_create_inode
      and remove one set of locking. Also this removes the loop in
      gfs2_create and simplifies the code a bit.

      GFS2: Use ->dirty_inode() · ab9bbda0
      Steven Whitehouse 提交于
      The aim of this patch is to use the newly enhanced ->dirty_inode()
      super block operation to deal with atime updates, rather than
      piggy backing that code into ->write_inode() as is currently
      done.
      
      The net result is a simplification of the code in various places
      and a reduction of the number of gfs2_dinode_out() calls since
      this is now implied by ->dirty_inode().
      
      Some of the mark_inode_dirty() calls have been moved under glocks
      in order to take advantage of then being able to avoid locking in
      ->dirty_inode() when we already have suitable locks.
      
      One consequence is that generic_write_end() now correctly deals
      with file size updates, so that we do not need a separate check
      for that afterwards. This also, indirectly, means that fdatasync
      should work correctly on GFS2 - the current code always syncs the
      metadata whether it needs to or not.
      
      Has survived testing with postmark (with and without atime) and
      also fsx.

      GFS2: Fix bug trap and journaled data fsync · f1818529
      Steven Whitehouse 提交于
      Journaled data requires that a complete flush of all dirty data for
      the file is done, in order that the ail flush which comes after
      will succeed.
      
      Also the recently enhanced bug trap can trigger falsely in case
      an ail flush from fsync races with a page read. This updates the
      bug trap such that it will ignore buffers which are locked and
      only trigger on dirty and/or pinned buffers when the ail flush
      is run from fsync. The original bug trap is retained when ail
      flush is run from ->go_sync()

      GFS2: Fix inode allocation error path · 40ac218f
      Steven Whitehouse 提交于
      If we have got far enough through the inode allocation code
      path that an inode has already been allocated, then we must
      call iput to dispose of it, if an error occurs during a
      later part of the process. This will always be the final iput
      since there will be no other references to the inode.
      
      Unlike when the inode has been unlinked, its block state will
      be GFS2_BLKST_INODE rather than GFS2_BLKST_UNLINKED so we need
      to skip the test in ->evict_inode() for this one case in order
      to ensure that it will be deallocated correctly. This patch adds
      a new flag in order to ensure that this will happen correctly.

      GFS2: Make atime checks more efficient · 1d4ec642
      Steven Whitehouse 提交于
      We do not need to start a transaction unless the atime
      check has proved positive. Also if we are going to flush
      the complete ail list anyway, we might as well skip the
      writeback for this specific inode's metadata, since that
      will be done as part of the ail writeback process in an
      order offering potentially more efficient I/O.

      GFS2: Fix bug-trap in ail flush code · 75549186
      Steven Whitehouse 提交于
      The assert was being tested under the wrong lock, a
      legacy of the original code. Also, if it does trigger,
      the resulting information was not always a lot of help.
      
      This moves the patch under the correct lock and also
      prints out more useful information in tacking down the
      source of the problem.

      GFS2: Split data write & wait in fsync · 2f0264d5
      Steven Whitehouse 提交于
      Now that the data writing is part of fsync proper, we can split
      the waiting part out and do it later on. This reduces the
      number of waits that we do during fsync on average.
      
      There is also no need to take the i_mutex unless we are flushing
      metadata to disk, so we can move that to within the metadata
      flushing code.

      GFS2: Clean up dir hash table reading · 4c28d338

      Since there is now only a single caller to gfs2_dir_read_data()
      and it has a number of constant arguments, we can factor
      those out. Also some tests relating to the inode size were
      being done twice.
