Subject: [PATCH] mm: dump page when hitting a VM_BUG_ON using VM_BUG_ON_PAGE fix
Date: Fri, 27 Dec 2013 17:40:18 -0500	[thread overview]
Message-ID: <1388184018-11396-1-git-send-email-sasha.levin@oracle.com> (raw)

I messed up and forgot to commit this fix before sending out the original
patch.

It fixes build issues in various files using VM_BUG_ON_PAGE.
