---------------------------
whiteout inode should be put when do_tmpfile() failed if inode has been initialized. Otherwise we will get following warning during umount: UBIFS error (ubi0:0 pid 1494): ubifs_assert_failed [ubifs]: UBIFS assert failed: c->bi.dd_growth == 0, in fs/ubifs/super.c:1930 VFS: Busy inodes after unmount of ubifs. Self-destruct in 5 seconds.
