bcache: fix cache_set_flush() NULL pointer dereference on OOM When bch_cache_set_alloc() fails to kzalloc the cache_set, the asyncronous closure handling tries to dereference a cache_set that hadn't yet been allocated inside of cache_set_flush() which is called by __cache_set_unregister() during cleanup. This appears to happen only during an OOM condition on bcache_register. Signed-off-by: Eric Wheeler <bcache@linux.ewheeler.net> Cc: stable@vger.kernel.org
