From 10be22dfe1e6ad978269dc275147e0ed049187bb Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 16 Sep 2009 11:50:04 +0200 Subject: HWPOISON: Export some rmap vma locking to outside world Needed for later patch that walks rmap entries on its own. This used to be very frowned upon, but memory-failure.c does some rather specialized rmap walking and rmap has been stable for quite some time, so I think it's ok now to export it.
