From 78efac537de33faab9a4302cc05a70bb4a8b3b63 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Mon, 22 Oct 2018 23:24:28 +0800 Subject: f2fs: fix to account IO correctly for cgroup writeback Now, we have supported cgroup writeback, it depends on correctly IO account of specified filesystem. But in commit d1b3e72d5490 ("f2fs: submit bio of in-place-update pages"), we split write paths from f2fs_submit_page_mbio() to two: - f2fs_submit_page_bio() for IPU path - f2fs_submit_page_bio() for OPU path But still we account write IO only in f2fs_submit_page_mbio(), result in incorrect IO account, fix it by adding missing IO account in IPU path.
