Oscar Ou has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1223165?usp=email ) Change subject: Fix cid_mutex deadlock in reserve_lease_or_expire ...................................................................... Fix cid_mutex deadlock in reserve_lease_or_expire In reserve_lease_or_expire(), cid_mutex it held first. If the lease is expired, it decreases the state owner reference by calling dec_state_owner_ref(), then it turn acquires the cid_mutex inside the free_nfs4_owner(). To prevent this deadlock, dec_state_owner_ref() should be called outside the the cid_mutex.
