Subject: [TRIVIAL] Trivial patch in the bootmem allocator
Date: Fri, 13 Sep 2002 15:38:55 +0200 [thread overview]
Message-ID: <20020913133855.GA623@apocalipsis> (raw)
If the requested align is PAGE_SIZE, it is impossible to merge with the
previous allocation request, because the allocated area must begin in a
page boundary.
Regards,
Juanma
