From: Pavel Begunkov <asml.silence@...il.com>
To: Jens Axboe <axboe@...nel.dk>, io-uring@...r.kernel.org,
linux-kernel@...r.kernel.org
Subject: [PATCH] io_uring: use labeled array init in io_op_defs
Don't rely on implicit ordering of IORING_OP_ and explicitly place them
at a right place in io_op_defs. Now former comments are now a part of
the code and won't ever outdate.
