From da8b066262e12d1d0a3b1e6d3486e500169bf730 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 13 Apr 2012 13:11:29 -0700 Subject: blkcg: make blkg_conf_prep() take @pol and return with queue lock held Add @pol to blkg_conf_prep() and let it return with queue lock held (to be released by blkg_conf_finish()). Note that @pol isn't used yet. This is to prepare for per-queue policy activation and doesn't cause any visible difference.
