Subject: f2fs: fix a wrong condition in f2fs_skip_inode_update
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=235831d7dd783ebd20e08ef4310dbdeeea46d87a;p=openwrt%2Fstaging%2Fblogic.git

f2fs: fix a wrong condition in f2fs_skip_inode_update

Fix commit 97dd26ad8347 (f2fs: fix wrong AUTO_RECOVER condition).
We should use ~PAGE_MASK to determine whether i_size is aligned to
the f2fs's block size or not.
