Malahal has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/489939 ) Change subject: Do lock_list empty check under the state lock. ...................................................................... Do lock_list empty check under the state lock. Two threads could execute state_release_grant() at the same time and they both could find the list empty leading to both calling put_ref on the object. Have the empty list check under state lock to avoid this.
