[PATCH 2/2] f2fs: fix to remove directory inode from dirty list

From: Chao Yu
Date: Tue Nov 10 2015 - 05:45:55 EST


If last dirty dentry page was writebacked in reclaim path, we should
remove its directory inode from global dirty list to avoid unnecessary
flush for this inode when doing checkpoint.
