Hm. How do you test this? From x86 point of view, this patch seems unnecessary because hugetlb_fault call "address &= hugetlb_mask()" at first and then migration_entry_wait() could grab right pte lock. And from !x86 point of view, this funciton still doesn't work because huge page != pmd on some arch. I might be missing something though. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
