[Cluster-devel] [PATCH 00/12] gfs2: punch hole

[Andreas Gruenbacher]

These patches fix a few minor issues in the non-recursive delete
implementation, add upper bound parameters so that these functions can
be used for punching holes in addition to truncating files at a given
position, and implement the fallocate hole punching operation base don
that.

These patches pass xfstests, but they haven't been tested very heavily
beyond that.

Andreas Gruenbacher (11):
  gfs2: Remove pointless BUG_ON
  gfs2: Clean up trunc_start error path
  gfs2: truncate: Remove unnecessary oldsize parameters
  gfs2: Remove minor gfs2_journaled_truncate inefficiencies
  gfs2: Clean up {lookup,fillup}_metapath
  gfs2: Fix metadata read-ahead during truncate
  gfs2: Improve non-recursive delete algorithm
  Turn gfs2_block_truncate_page into gfs2_block_zero_range
  gfs2: Generalize truncate code
  gfs2: Turn trunc_dealloc into punch_hole
  gfs2: Implement fallocate(FALLOC_FL_PUNCH_HOLE)

Steven Whitehouse (1):
  gfs2: Add gfs2_blk2rgrpd comment and fix incorrect use
