From 57292b58ddb58689e8c3b4c6eadbef10d9ca44dd Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 31 Jan 2017 16:57:29 +0100 Subject: [PATCH] block: introduce blk_rq_is_passthrough This can be used to check for fs vs non-fs requests and basically removes all knowledge of BLOCK_PC specific from the block layer, as well as preparing for removing the cmd_type field in struct request.
