Subject: Removed vax ifdefed function from kern_subr.c (from NetBSD).
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=f657594cc26df9d9ba94aa1b70c4599e849a2ef2;p=openbsd

Removed vax ifdefed function from kern_subr.c (from NetBSD).
Do sync in the order of umount (vfs_syscals.c), as it was pointed
by someone in NetBSD's lists.
