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
