[Cluster-devel] [GFS2 PATCH 0/3] fallocate quota fixes

[Abhi Das <adas@redhat.com>]

This is a revised set of patches for bz1174295 to address
fallocate/quota issues. These patches are only compile
tested so far.

patch 1 - This is the patch that actually addresses the quota
	  exceed issue. Quota checks were not being performed
	  against the blocks about to be allocated.

patch 2 - Modify gfs2_inplace_reserve() and gfs2_quota_check()
	  to return available number of blocks in case of
	  failure.

patch 3 - Allows fallocate to take advantage of patch 2 to
	  efficiently max out quotas or fill up the fs instead
	  of returning -EDQUOT/-ENOSPC and leaving some
	  available blocks unallocated.

Abhi Das (3):
  gfs2: perform quota checks against allocation parameters
  gfs2: allow quota_check and inplace_reserve to return available blocks
  gfs2: allow fallocate to max out quotas/fs efficiently
