Fix posted to rhkernel-list with Message-ID: <20101025173439.GM910> I removed the false positive BUG_ON and introduced one new VM_BUG_ON in a s/!pmd_present/pmd_none/ related place, the VM_BUG_ON introduced will be converted to BUG_ON to exercise it in the build that I will provide to QA. The build system I use has disk full problem, as soon as it's fixed I'll provide a build with patch included. Thanks! Build with fix in comment #3 included (with VM_BUG_ON converted to BUG_ON) here: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=2850419 This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release.
