Caller
NameDescribe
filemap_map_pages
do_swap_pageWe enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults), and pte mapped but not yet locked.* We return with pte unmapped and unlocked.* We return with the mmap_sem locked or unlocked in the same cases
__do_faultThe 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_pagesThis 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_errorError injection support for memory error handling.
dequeue_huge_page_node_exact
dissolve_free_huge_pageDissolve a given free hugepage into free buddy pages. This function does* nothing for in-use hugepages and non-hugepages.* This function returns values like below:* -EBUSY: failed to dissolved free hugepages or the hugepage is in-use
hugetlb_no_page
clear_hwpoisoned_pages
uncharge_page
memory_failure_hugetlb
memory_failurememory_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_memorypoison_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
soft_offline_pagesoft_offline_page - Soft offline a page.*@pfn: pfn to soft-offline*@flags: flags. Same as memory_failure().* Returns 0 on success, otherwise negated errno.* Soft offline a page, by migration or invalidation,* without killing anything
__test_page_isolated_in_pageblockTest all pages in the range is free(means isolated) or not.* all pages in [start_pfn...end_pfn) must be in the same zone.* zone->lock must be held before call this.* Returns the last tested pfn.
