cluster/afr: Fix witness counting code in src/sink detection
Problem: In afr-v1 pre-op, xattrop increments self xattr first then it increments the value on rest. In post-op, xattr value is decreased first on rest and at last it gets decremented on self. So for a possible operation to be witnessed i.e. a fop is seen by the brick it is important to have at least 1 pending op because without completing pre-op fop won't come. The other possibility is when fop completes but at the time of post-op after decrementing pending counts on others just before decrementing its own pending count, the brick dies. Fix: Fix witness detection code in afr_self_heal_find_direction() BUG: 1322253 Change-Id: Ia7e76482c0a46e775e269bb96ec1b9490a3ac18f Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/13811 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Ravishankar N <ravishankar@redhat.com>
