WARNING: possible circular locking dependency detected

------------------------------------------------------
syz-executor.2/11438 is trying to acquire lock:
0000000012bcc033 (&fs_info->qgroup_ioctl_lock){+.+.}, at: btrfs_qgroup_inherit+0xde/0x1c60 fs/btrfs/qgroup.c:2284

but task is already holding lock:
0000000074fd86d6 (sb_internal#2){.+.+}, at: sb_start_intwrite include/linux/fs.h:1626 [inline]
0000000074fd86d6 (sb_internal#2){.+.+}, 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:
