      GFS2: Merge lock_dlm module into GFS2 · f057f6cd
      Steven Whitehouse authored
      This is the big patch that I've been working on for some time
      now. There are many reasons for wanting to make this change
      such as:
       o Reducing overhead by eliminating duplicated fields between structures
       o Simplifcation of the code (reduces the code size by a fair bit)
       o The locking interface is now the DLM interface itself as proposed
         some time ago.
       o Fewer lookups of glocks when processing replies from the DLM
       o Fewer memory allocations/deallocations for each glock
       o Scope to do further optimisations in the future (but this patch is
         more than big enough for now!)
      
      Please note that (a) this patch relates to the lock_dlm module and
      not the DLM itself, that is still a separate module; and (b) that
      we retain the ability to build GFS2 as a standalone single node
      filesystem with out requiring the DLM.
      
      This patch needs a lot of testing, hence my keeping it I restarted
      my -git tree after the last merge window. That way, this has the maximum
      exposure before its merged. This is (modulo a few minor bug fixes) the
      same patch that I've been posting on and off the the last three months
      and its passed a number of different tests so far.

      GFS2: Remove "double" locking in quota · 22077f57
      Steven Whitehouse authored
      We only really need a single spin lock for the quota data, so
      lets just use the lru lock for now.

      GFS2: change gfs2_quota_scan into a shrinker · 0a7ab79c
      Abhijith Das authored
      Deallocation of gfs2_quota_data objects now happens on-demand through a
      shrinker instead of routinely deallocating through the quotad daemon.

      GFS2: Bring back lvb-related stuff to lock_nolock to support quotas · 2db2aac2
      Abhijith Das authored
      The quota code uses lvbs and this is currently not implemented in
      lock_nolock, thereby causing panics when quota is enabled with
      lock_nolock. This patch adds the relevant bits.

      GFS2: Fix remount argument parsing · 6f04c1c7
      Steven Whitehouse authored
      The following patch fixes an issue relating to remount and argument
      parsing. After this fix is applied, remount becomes atomic in that
      it either succeeds changing the mount to the new state, or it fails
      and leaves it in the old state. Previously it was possible for the
      parsing of options to fail part way though and for the fs to be left
      in a state where some of the new arguments had been applied, but some
      had not.
