syz-executor360/5861 is trying to acquire lock:
ffff88803113a7a0 (&htab->lockdep_key#323){..-.}-{2:2}, at: htab_lock_bucket+0x1a4/0x370 kernel/bpf/hashtab.c:167

but task is already holding lock:
ffff888028c55ba0 (&htab->lockdep_key#325){....}-{2:2}, at: htab_lock_bucket+0x1a4/0x370 kernel/bpf/hashtab.c:167

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:
