On the naming issue, see my other message from a few days ago. Concerning
the added complexity and the need-for-cleanup in init/do_mounts_initrd.c, I
have added the following comment:

In the near future, the only fs-external caller of ksys_umount() should be
converted to call do_umount() directly. Then, ksys_umount() can be moved
within sys_umount() again.
