syz-executor4/11290 is trying to acquire lock:

kobject: 'loop2' (000000008482d753): kobject_uevent_env

but task is already holding lock:
00000000da1edc55 (&lo->lo_ctl_mutex#2){+.+.}, at: lo_compat_ioctl+0x11b/0x170 drivers/block/loop.c:1592

which lock already depends on the new lock.

kobject: 'loop2' (000000008482d753): fill_kobj_path: path = '/devices/virtual/block/loop2'

the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  &bdev->bd_mutex --> loop_index_mutex --> &lo->lo_ctl_mutex#2

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&lo->lo_ctl_mutex#2);
                               lock(loop_index_mutex);
                               lock(&lo->lo_ctl_mutex#2);
  lock(&bdev->bd_mutex);
