[Cluster-devel] [PATCH v2 00/20] Some log space management cleanups

[Andreas Gruenbacher <agruenba@redhat.com>]

Hello,

here's an update on the log log space management cleanup.  The
notable additions are:

* gfs2: Get rid of current_tail()

  Replace current_tail() with a new sd_log_flush_tail variable in
  the super block.

* gfs2: No revokes for transactions at the tail of the log

  We no longer write out revokes for transactions at the tail
  of the log that have completed; the log header with its
  updated lh_tail will implicitly take care of revoking those.

* gfs2: Rework the log space allocation logic

  Clean up the entire log space allocation code to make it
  more manageable.

* gfs2: Hand out revokes to transactions one by one

  Based on the previous patch, clean up the revoke allocation
  code.

Thanks,
Andreas
