WARNING: possible recursive locking detected
6.9.0-rc1-syzkaller #0 Not tainted
--------------------------------------------
syz-executor/4691 is trying to acquire lock:
ffff88813bd2c320 (lock#9){+.+.}-{2:2}, at: local_lock_acquire include/linux/local_lock_internal.h:29 [inline]
ffff88813bd2c320 (lock#9){+.+.}-{2:2}, at: __mmap_lock_do_trace_acquire_returned+0x3e/0x200 mm/mmap_lock.c:237

but task is already holding lock:
ffff88813bd2c320 (lock#9){+.+.}-{2:2}, at: local_lock_acquire include/linux/local_lock_internal.h:29 [inline]
ffff88813bd2c320 (lock#9){+.+.}-{2:2}, at: __mmap_lock_do_trace_acquire_returned+0x3e/0x200 mm/mmap_lock.c:237

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(lock#9);
  lock(lock#9);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
