Subject: f2fs: don't need to invalidate wrong node page
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4f295443bff1701430249beec5eb9dc875decc9c;p=openwrt%2Fstaging%2Fblogic.git

f2fs: don't need to invalidate wrong node page

If f2fs_new_inode() is failed, the bad inode will invalidate 0'th node page
during f2fs_evict_inode(), which doesn't need to do.
