From 934031a12980511c020acf7d91f9035e34d0b5b8 Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Wed, 9 May 2018 02:08:47 -0700 Subject: block: move some wbt helpers to blk-wbt.c A few helpers are only used from blk-wbt.c, so move them there, and put wbt_track() behind the CONFIG_BLK_WBT typedef. This is in preparation for changing how the wbt flags are tracked.
