From bb68d504f7c4183178b00c1af68fca870728e7e0 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 29 Apr 2022 09:25:12 -0600 Subject: [PATCH] io_uring: ignore ->buf_index if REQ_F_BUFFER_SELECT isn't set There's no point in validity checking buf_index if the request doesn't have REQ_F_BUFFER_SELECT set, as we will never use it for that case.
