System: FreeBSD kan.dnsalias.net 5.0-CURRENT FreeBSD 5.0-CURRENT #3: Thu Jun 14 21:29:05 EDT 2001 root@kan.dnsalias.net:/usr/src/sys/compile/KAN i386

>Description:
	In its current state, it is impossible to load umapfs.ko module
	without getting "exec format error message" from kldload due to
	missing null_bypass symbol.
>How-To-Repeat:
	kldload umapfs
>Fix:
	Attached patch add required MODULE_DEPEND statement to the umap_vfsops.c
	file and MODULE_VERSION to the null_vfsops.c file. Version 1 has been 
	choosen for nullfs.ko somewhat arbitrary :)
