   I don't like it either, but this is a special case, yes. See:
   
   
http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA1999-006.txt.asc
   
   and
   
   
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/miscfs/umapfs/umap_vfsops.c#rev1.21


in this case, i'd rather some non-FS specific name that would also
be useful for other code that implements umapfs-like-functionality.

that's really as simple as calling it KAUTH_REQ_SYSTEM_MOUNT_USERMAP
or something, i guess.

(hmm, doesn't nfs have some of this in newer versions?)
