__do_fault	The mmap_sem must have been held on entry, and may have been* released depending on flags and vma->vm_ops->fault() return value.* See filemap_fault() and __lock_page_retry().
try_to_unmap_one	@arg: enum ttu_flags will be passed to this argument
has_unmovable_pages	This function checks whether pageblock includes unmovable pages or not.* If @count is not zero, it is okay to include less @count unmovable pages* PageLRU check without isolation or lru_lock could race so that
madvise_inject_error	Error injection support for memory error handling.
dequeue_huge_page_node_exact

uncharge_page
memory_failure_hugetlb
memory_failure	memory_failure - Handle memory failure of a page.@pfn: Page Number of the corrupted page@flags: fine tune action taken* This function is called by the low level machine check code* of an architecture when it detects hardware memory corruption* of a page
unpoison_memory	poison_memory - Unpoison a previously poisoned page@pfn: Page number of the to be unpoisoned page Software-unpoison a page that has been poisoned by* memory_failure() earlier
soft_offline_huge_page
__soft_offline_page
