Subject: Re: [PATCH] MM: Support more pagesizes for MAP_HUGETLB/SHM_HUGETLB v6
Date: Tue, 23 Oct 2012 15:39:52 +0200 [thread overview]
Message-ID: <20121023133952.GC16230@one.firstfloor.org> (raw)

I thought further about this and I think the whole issue is a non issue
anyways: MAP_UNINITIALIZED is NOMMU only and HUGETLBFS is MMU only.
My flags only make sense with HUGETLBFS.
So they can never coexist anyways. So there is no reason to not overlap.
So I think the original patch is ok and doesn't need any change at all.
Sorry guys, if you really want to invent new syscalls please do it
yourself.
