Not really. Hugetlbfs needs to be kept around for a number of reasons. It was designed to support MAP_SHARED mappings and IPC shm segments. It is probably still the best interface for those jobs. Of course hugetlbfs has lots of users so we must preserve the interface for them. But... once hugetlbfs is abstracted behind pagetable_operations, you would have the option of configuring it out of the kernel without losing access to huge pages by other means (such as the character device). -- 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 [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
