* Allow the kernel to initiate a freeze of a filesystem. The kernel
and userspace can both hold a freeze on a filesystem at the same
time; the freeze is not lifted until /both/ holders lift it. This
will enable us to fix a longstanding bug in XFS online fsck.
* Use kernel-initated fsfreeze to fix some longstanding false negatives
in onlin fsck of the free space and inode counters.
