From 547b1e81afe3119f7daf702cc03b158495535a25 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 9 Oct 2012 21:06:41 +0900 Subject: [PATCH] Fix staging driver use of VM_RESERVED The VM_RESERVED flag was killed off in commit 314e51b9851b ("mm: kill vma flag VM_RESERVED and mm->reserved_vm counter"), and replaced by the proper semantic flags (eg "don't core-dump" etc). But there was a new use of VM_RESERVED that got missed by the merge. Fix the remaining use of VM_RESERVED in the vfio_pci driver, replacing the VM_RESERVED flag with VM_DONTEXPAND | VM_DONTDUMP.
