Subject: [PATCH tip/core/rcu 24/30] rcu/nocb: Add missing annotation for rcu_nocb_bypass_unlock()

From: Jules Irenge <>

Sparse reports warning at rcu_nocb_bypass_unlock()

warning: context imbalance in rcu_nocb_bypass_unlock() - unexpected unlock

The root cause is a missing annotation of rcu_nocb_bypass_unlock()
which causes the warning.

This commit therefore adds the missing __releases(&rdp->nocb_bypass_lock)
