Subject: f2fs: call f2fs_balance_fs for setattr
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=15d04354555fdfe8005e1365009e349148fb5f90;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

f2fs: call f2fs_balance_fs for setattr

If inode becomes dirty, we need to check the # of dirty inodes whether or not
further checkpoint would be required.
