ocfs2: add missing annotations for ocfs2_refcount_cache_lock() and ocfs2_refcount_cache_unlock()
Sparse reports warnings at ocfs2_refcount_cache_lock()
and ocfs2_refcount_cache_unlock()
warning: context imbalance in ocfs2_refcount_cache_lock()
- wrong count at exit
warning: context imbalance in ocfs2_refcount_cache_unlock()
- unexpected unlock
The root cause is the missing annotation at ocfs2_refcount_cache_lock()
and at ocfs2_refcount_cache_unlock()
Add the missing __acquires(&rf->rf_lock) annotation to
ocfs2_refcount_cache_lock()
Add the missing __releases(&rf->rf_lock) annotation to
ocfs2_refcount_cache_unlock()
