Subject[PATCH 11/11] futex: Add missing annotation for futex_wait_queue_me()
Date
Sparse reports a warning at futex_wait_queue_me()

warning: context imbalance in futex_wait_queue_me() - unexpected unlock

The root cause is a missing annotation at futex_wait_queue_me()

Add the missing annotation __releases(&hb->lock)
