      [GFS2] Update copyright, tidy up incore.h · e9fc2aa0
      Steven Whitehouse 提交于
      As per comments from Jan Engelhardt <jengelh@linux01.gwdg.de> this
      updates the copyright message to say "version" in full rather than
      "v.2". Also incore.h has been updated to remove forward structure
      declarations which are not required.
      
      The gfs2_quota_lvb structure has now had endianess annotations added
      to it. Also quota.c has been updated so that we now store the
      lvb data locally in endian independant format to avoid needing
      a structure in host endianess too. As a result the endianess
      conversions are done as required at various points and thus the
      conversion routines in lvb.[ch] are no longer required. I've
      moved the one remaining constant in lvb.h thats used into lm.h
      and removed the unused lvb.[ch].
      
      I have not changed the HIF_ constants. That is left to a later patch
      which I hope will unify the gh_flags and gh_iflags fields of the
      struct gfs2_holder.

      [GFS2] Fix unlinked file handling · feaa7bba
      Steven Whitehouse 提交于
      This patch fixes the way we have been dealing with unlinked,
      but still open files. It removes all limits (other than memory
      for inodes, as per every other filesystem) on numbers of these
      which we can support on GFS2. It also means that (like other
      fs) its the responsibility of the last process to close the file
      to deallocate the storage, rather than the person who did the
      unlinking. Note that with GFS2, those two events might take place
      on different nodes.
      
      Also there are a number of other changes:
      
       o We use the Linux inode subsystem as it was intended to be
      used, wrt allocating GFS2 inodes
       o The Linux inode cache is now the point which we use for
      local enforcement of only holding one copy of the inode in
      core at once (previous to this we used the glock layer).
       o We no longer use the unlinked "special" file. We just ignore it
      completely. This makes unlinking more efficient.
       o We now use the 4th block allocation state. The previously unused
      state is used to track unlinked but still open inodes.
       o gfs2_inoded is no longer needed
       o Several fields are now no longer needed (and removed) from the in
      core struct gfs2_inode
       o Several fields are no longer needed (and removed) from the in core
      superblock
      
      There are a number of future possible optimisations and clean ups
      which have been made possible by this patch.

      [GFS2] Further updates to dir and logging code · 71b86f56
      Steven Whitehouse 提交于
      This reduces the size of the directory code by about 3k and gets
      readdir() to use the functions which were introduced in the previous
      directory code update.
      
      Two memory allocations are merged into one. Eliminates zeroing of some
      buffers which were never used before they were initialised by
      other data.
      
      There is still scope for further improvement in the directory code.
      
      On the logging side, a hand created mutex has been replaced by a
      standard Linux mutex in the log allocation code.

      [GFS2] Fix bug in directory code and tidy up · c752666c
      Steven Whitehouse 提交于
      Due to a typo, the dir leaf split operation was (for the first
      split in a directory) writing the new hash vaules at the
      wrong offset. This is now fixed.
      
      Also some other tidy ups are included:
      
       - We use GFS2's hash function for dentries (see ops_dentry.c) so that
         we don't have to keep recalculating the hash values.
       - A lot of common code is eliminated between the various directory
         lookup routines.
       - Better error checking on directory lookup (previously different
         routines checked for different errors)
       - The leaf split operation has a couple of redundant operations
         removed from it, so it should be faster.
      
      There is still further scope for further clean ups in the directory
      code, and readdir in particular could do with slimming down a bit.

      [GFS2] Macros removal in gfs2.h · 5c676f6d
      Steven Whitehouse 提交于
      As suggested by Pekka Enberg <penberg@cs.helsinki.fi>.
      
      The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h
      The other macros are gone from gfs2.h as (although not requested
      by Pekka Enberg) are a number of included header file which are now
      included individually. The inode number comparison function is
      now an inline function.
      
      The DT2IF and IF2DT may be addressed in a future patch.
