syz-executor.2/13070 is trying to acquire lock:

but task is already holding lock:

000000001601fe1c (&nbd->config_lock){+.+.}, at: refcount_dec_and_mutex_lock+0x4a/0x80 lib/refcount.c:306

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

Chain exists of:
