Hierarchical stats for cfq-iosched will need __blkg_prfill_rwstat(). Export it. Signed-off-by: Tejun Heo <tj@xxxxxxxxxx> Reported-by: Fengguang Wu <fengguang.wu@xxxxxxxxx> --- Fengguang's build test discovered that cfq now uses __blkg_prfill_rwstat() which isn't exported leading to build failures when cfq is built as a module. Export it. This doesn't affect !module builds. Git branch updated accordingly.
