We have name and fsid in the new device spec format, but kernel just
discard them.  Instead of relying on the mount.ceph helper, we should do
this directly in kernel to ensure the options and device spec are
consistent.  And also avoid any confusion.

Hu Weiwen (3):
  ceph: refactor mds_namespace comparing
  ceph: save name and fsid in mount source
  libceph: reject mismatching name and fsid
