Can we give hugetlb demand faulting a spin in the mm tree? And could people with alpha, sparc, and ia64 machines give them a good spin? I haven't been able to test those arches yet. -Thanks - htlb-get_user_pages removes an optimization that is no longer valid when demand faulting huge pages - htlb-fault moves the fault logic from hugetlb_prefault() to hugetlb_pte_fault() and find_get_huge_page(). - htlb-acct adds an overcommit check to maintain the no-overcommit semantics provided by hugetlb_prefault() -- Adam Litke - (agl at us.ibm.com) IBM Linux Technology Center - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
