From b9610bdfcbdbb6017802ec6d1e073f445c98157d Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 14 Oct 2016 13:28:05 -0700 Subject: [PATCH] f2fs: count dirty inodes to flush node pages during checkpoint If there are a lot of dirty inodes, we need to flush all of them when doing checkpoint. So, we need to count this for enough free space.
