Originally, we just held the frwd_lock the entire time but in\ncommit bcf3a2953d36 (\"scsi: iscsi: iscsi_tcp: Avoid holding spinlock while\ncalling getpeername()\") we switched to refcount based because the network\nlayer changed and started taking a mutex in that path, so we could no\nlonger hold the frwd_lock.\n\nInstead of trying to maintain multiple refcounts, this just has us use a\nmutex for accessing the socket in the interface code paths."
