Jens Axboe 7644b1a1c9 io_uring/fdinfo: lock SQ thread while retrieving thread cpu/pid ... We could race with SQ thread exit, and if we do, we'll hit a NULL pointer dereference when the thread is cleared. Grab the SQPOLL data lock before attempting to get the task cpu and pid for fdinfo, this ensures we have a stable view of it.
