>Description:

        1) Fix bug in mount_umap that will be committed after freeze is lifted.

        2) mount_umap -u /tmp/uidfile -g /tmp/gidfile /tmp /tmp

        This ought to insert a `umap' layer into the existing UFS structure
        under /tmp.  Instead, I get a `panic: ufs_ihashget: recursive lock 
        not expected -- pid %d'. Unfirtunately, I didn't save the core
        dump, so I can't provide a traceback.

	/tmp is on the root filesystem on my machine.

	as above
