Hello Linus Sorry for the 2nd pull request, but this is a fairly important fix for the privilege handling of smackfs in the face of io_uring. The novel use of kernel threads in io_uring invalidated an long standing assumption regarding the privilege of kernel threads. The fix is simple and safe. It was provided by Jens Axboe <ax...@kernel.dk> and has been tested.
