Subject: SRCU: add lock annotations to srcu_read_lock and srcu_read_unlock
From: Josh Triplett <josht@xxxxxxxxxx>
Add an __acquires annotation to srcu_read_lock, and add a __releases
annotation to srcu_read_unlock. This allows static analysis tools to
detect improperly paired calls to these functions.
