sparse, being a static analyzer, emits the following warnings: context imbalance in 'nfs_server_list_start' - wrong count at exit context imbalance in 'nfs_server_list_start' - unexpected unlock context imbalance in 'nfs_volume_list_start' - wrong count at exit context imbalance in 'nfs_volume_list_start' - unexpected unlock
Help it by annotating the pairs of functions with __acquires and __releases.
