[Cluster-devel] [GFS2 v4 PATCH 00/25] gfs2: misc recovery patch collection

[Bob Peterson <rpeterso@redhat.com>]

Here is version 4 of the patch set I posted on 23 April. It is revised
based on bugs I found testing with xfstests.

The first 8 are cleanups, the rest are bug fixes.

This is a collection of patches I've been using to address the myriad
of recovery problems I've found. There aren't many other dependencies
between patches, so many could be accepted or rejected individually.

Bob Peterson (25):
  gfs2: kthread and remount improvements
  gfs2: eliminate tr_num_revoke_rm
  gfs2: log which portion of the journal is replayed
  gfs2: Warn when a journal replay overwrites a rgrp with buffers
