From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 021b77bee210843bed1ea91b5cad58235ff9c8e5 upstream.
Probably this code was syncing a lot more often then intended because
the do_sync variable wasn't set to zero.
Fixes: c62988ec0910 ('ceph: avoid meaningless calling ceph_caps_revoking if sync_mode == WB_SYNC_ALL.')
