------------------------------------------------------
syz-executor7/21968 is trying to acquire lock:
 (&ctx->mutex){+.+.}, at: [<00000000155023ed>] perf_event_ctx_lock_nested+0x21b/0x450 kernel/events/core.c:1249

but task is already holding lock:
 (&pipe->mutex/1){+.+.}, at: [<00000000077d3e82>] pipe_lock_nested fs/pipe.c:67 [inline]
 (&pipe->mutex/1){+.+.}, at: [<00000000077d3e82>] pipe_lock+0x56/0x70 fs/pipe.c:75

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:
  &ctx->mutex --> sb_writers --> &pipe->mutex/1

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&pipe->mutex/1);

                               lock(&pipe->mutex/1);
