From 511116669346a0029b7e54eaaa8e5a7029f89ab3 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Sun, 5 Jun 2016 14:31:46 -0500 Subject: dm: use op_is_write instead of checking for REQ_WRITE We currently set REQ_WRITE/WRITE for all non READ IOs like discard, flush, writesame, etc. In the next patches where we no longer set up the op as a bitmap, we will not be able to detect a operation direction like writesame by testing if REQ_WRITE is set. This has dm use the op_is_write helper which will do the right thing.
