This means that when the pipe is ultimately freed,\nwe decrement user->pipe_bufs by something other than what than we had\ncharged to it, potentially leading to an underflow. This in turn can\ncause subsequent too_many_pipe_buffers_soft() tests to fail with -EPERM.\n\nTo remedy this, explicitly account for the pipe usage in\nwatch_queue_set_size() to match the number set via account_pipe_buffers()\n\n(It's unclear why watch_queue_set_size() does not update nr_accounted;\nit may be due to intentional overprovisioning in watch_queue_set_size()?)"
