WARNING: possible circular locking dependency detected

------------------------------------------------------
syz-executor.2/11818 is trying to acquire lock:

but task is already holding lock:

00000000706be6d2 (sb_internal#4){.+.+}, at: start_transaction+0xa37/0xf90 fs/btrfs/transaction.c:528

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:
