[Cluster-devel] [PATCH 00/32] gfs2: misc recovery patch collection

[Bob Peterson <rpeterso@redhat.com>]

This is my latest collection of patches to address the myriad of gfs2
recovery problems I've found. I'm not convinced we need all of these
but I thought I'd send them anyway and get feedback

Some of these are just bugs and may be pushed separately.

Bob Peterson (32):
  gfs2: Introduce concept of a pending withdraw
  gfs2: clear ail1 list when gfs2 withdraws
  gfs2: Rework how rgrp buffer_heads are managed
  gfs2: fix infinite loop in gfs2_ail1_flush on io error
  gfs2: log error reform
  gfs2: Only complain the first time an io error occurs in quota or log
  gfs2: Ignore dlm recovery requests if gfs2 is withdrawn
  gfs2: move check_journal_clean to util.c for future use
  gfs2: Allow some glocks to be used during withdraw
  gfs2: Don't loop forever in gfs2_freeze if withdrawn
  gfs2: Make secondary withdrawers wait for first withdrawer
  gfs2: Don't write log headers after file system withdraw
  gfs2: Force withdraw to replay journals and wait for it to finish

  gfs2: Do log_flush in gfs2_ail_empty_gl even if ail list is empty
  gfs2: Don't skip log flush if glock still has revokes
  gfs2: initialize tr_ail1_list when creating transactions
  gfs2: Withdraw in gfs2_ail1_flush if write_cache_pages returns error
  gfs2: drain the ail2 list after io errors
  gfs2: make gfs2_log_shutdown static
  gfs2: Eliminate GFS2_RDF_UPTODATE flag in favor of buffer existence
  gfs2: if finish_open returns error, clean up iopen glock mess
