From dfec8a14fc9043039e3c04807caf39dc71102816 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Sun, 5 Jun 2016 14:31:44 -0500 Subject: [PATCH] fs: have ll_rw_block users pass in op and flags separately This has ll_rw_block users pass in the operation and flags separately, so ll_rw_block can setup the bio op and bi_rw flags on the bio that is submitted.
