>Organization:

>Environment:

	FreeBSD 2.0-BUILT-19950512 #395: Fri May 12 14:53:28 EDT 1995

>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.

>How-To-Repeat:

	as above

>Fix:

State-Changed-Why:  
This PR is a duplicate of #1067, which has a better description 
of the problem, so I opted to keep that one open to track 
this problem instead.
