Liu Bo 15d1ff8111 Btrfs: fix deadlock during allocating chunks ... This deadlock comes from xfstests 251. We'll hold the chunk_mutex throughout the whole of a chunk allocation. But if we find that we've used up system chunk space, we need to allocate a new system chunk, but this will lead to a recursion of chunk allocation and end up with a deadlock on chunk_mutex. So instead we need to allocate the system chunk first if we find we're in ENOSPC.
