syz.3.351/5765 is trying to acquire lock:

but task is already holding lock:

ffff0000deb89400 (mapping.invalidate_lock#9){.+.+}-{3:3}, at: page_cache_ra_unbounded+0x140/0x5dc mm/readahead.c:195

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  &ni->ni_lock/5 --> &mm->mmap_lock --> mapping.invalidate_lock#9

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(mapping.invalidate_lock#9);
