Subject: alloc_contiguous_pages() is supposed to round the allocation size to a page
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=95e992d0d7d7f899b3317b2c08c953747cc88323;p=openbsd

alloc_contiguous_pages() is supposed to round the allocation size to a page
boundary, not to an u area boundary. Oops.
