Chen, Kenneth W a43a8c39bb [PATCH] tightening hugetlb strict accounting ... Current hugetlb strict accounting for shared mapping always assume mapping starts at zero file offset and reserves pages between zero and size of the file. This assumption often reserves (or lock down) a lot more pages then necessary if application maps at none zero file offset. libhugetlbfs is one example that requires proper reservation on shared mapping starts at none zero offset. This patch extends the reservation and hugetlb strict accounting to support any arbitrary pair of (offset, len), resulting a much more robust and accurate scheme. More importantly, it won't lock down any hugetlb pages outside file mapping.
