Subject[PATCH 5/7] btrfs: Add missing annotation for btrfs_lock_cluster()
Date
Sparse reports a warning at btrfs_lock_cluster()

warning: context imbalance in btrfs_lock_cluster()
- wrong count

The root cause is the missing annotation at btrfs_lock_cluster()
Add the missing __acquires(&cluster->refill_lock) annotation.
