From 9a95e4ef709533efac4aafcb8bddf73f96db50ed Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 9 Nov 2017 10:49:59 -0800 Subject: block, nvme: Introduce blk_mq_req_flags_t Several block layer and NVMe core functions accept a combination of BLK_MQ_REQ_* flags through the 'flags' argument but there is no verification at compile time whether the right type of block layer flags is passed. Make it possible for sparse to verify this. This patch does not change any functionality.
