glusterd : introduce timer in mgmt_v3_lock
Problem: In a multinode environment, if two of the op-sm transactions are initiated on one of the receiver nodes at the same time, there might be a possibility that glusterd may end up in stale lock. Solution: During mgmt_v3_lock a registration is made to gf_timer_call_after which release the lock after certain period of time Change-Id: I16cc2e5186a2e8a5e35eca2468b031811e093843 BUG: 1499004 Signed-off-by: Gaurav Yadav <gyadav@redhat.com>
