Kent Overstreet 84759c6d18 Revert "rw_semaphore: remove up/down_read_non_owner" ... This reverts commit 11b80f459a. Bcache needs rw semaphores for cache coherency in writeback mode - writes have to take a read lock on a per cache device rw sem, and release it when the bio completes. But since this is for bios it's naturally not in the context of the process that originally took the lock.
