Subject: f2fs: fix por_doing variable coverage
X-Git-Tag: upstream/snapshot3+hdmi~4852^2~52
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8c26d7d5717adf7f06d98c4416852d09566edd7c;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

f2fs: fix por_doing variable coverage

The reason of using sbi->por_doing is to alleviate data writes during the
recovery.
The find_fsync_dnodes() produces some dirty dentry pages, so we should
cover it too with sbi->por_doing.
