afr: Add throttled background client-side heals
If a heal is needed after inode refresh (lookup, read_txn), launch it in the background instead of blocking the fop (that triggered refresh) until the heal happens. afr_replies_interpret() is modified such that the heal is launched only if atleast one sink brick is up. Max. no of heals that can happen in parallel is configurable via the 'background-self-heal-count' volume option. Any number greater than that is put in a wait queue whose length is configurable via 'heal-wait-queue-leng' volume option. If the wait queue is also full, further heals will be ignored. Default values: background-self-heal-count=8, heal-wait-queue-leng=128 Change-Id: I1d4a52814cdfd43d90591b6d2ad7b6219937ce70 BUG: 1297172 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/13207 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>
