      xfs: fix locking in xfs_iget_cache_hit · a022fe09
      Christoph Hellwig authored
      The locking in xfs_iget_cache_hit currently has numerous problems:
      
       - we clear the reclaim tag without i_flags_lock which protects
         modifications to it
       - we call inode_init_always which can sleep with pag_ici_lock
         held (this is oss.sgi.com BZ #819)
       - we acquire and drop i_flags_lock a lot and thus provide no
         consistency between the various flags we set/clear under it
      
      This patch fixes all that with a major revamp of the locking in
      the function.  The new version acquires i_flags_lock early and
      only drops it once we need to call into inode_init_always or before
      calling xfs_ilock.
      
      This patch fixes a bug seen in the wild where we race modifying the
      reclaim tag.

      GFS2: Fix permissions on "recover" file · d7e623da
      Steven Whitehouse authored
      Although this file is only ever written and not read by
      userspace, it seems that the utils are opening this
      file O_RDWR, so we need to allow that.
      
      Also fixes the whitespace which seemed to be broken.
