From: Jaegeuk Kim Date: Thu, 2 Jun 2016 18:08:56 +0000 (-0700) Subject: f2fs: avoid wrong count on dirty inodes X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=338bbfa086c34ed4ec33bd3c4c4a2ec89336a567;p=deliverable%2Flinux.git f2fs: avoid wrong count on dirty inodes The number should be covered by spin_lock. Otherwise we can see wrong count in f2fs_stat.
