That\nfunction may perform page migration on its own (some vmas may not contain page\nstructs and therefore cannot be handled by regular page migration. Pages in a\nvma may require special preparatory treatment before migration is possible\netc) . Only mmap_sem is held when the migration function is called. The\nmigrate() function gets passed two sets of nodemasks describing the source and\nthe target of the migration. The flags parameter either contains\n\nMPOL_MF_MOVE\twhich means that only pages used exclusively by\n\t\tthe specified mm should be moved\n\nor\n\nMPOL_MF_MOVE_ALL which means that pages shared with other processes\n\t\tshould also be moved.\n\nThe migration function returns 0 on success or an error condition. An error\ncondition will prevent regular page migration from occurring.\n\nOn its own this patch cannot be included since there are no users for this\nfunctionality. But it seems that the uncached allocator will need this\nfunctionality at some point.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "68402ddc677005ed1b1359bbc1f279548cfc0928", "tree": "83da62a2b55e2ea7e0c46ed79c0d6498d36e1942", "parents": [ "9f1a3cfcffaed2fbb3206179295c79ca8289f5c3" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Sun Jun 25 05:46:47 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jun 25 10:00:55 2006 -0700" }, "message": "[PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHM\n\nRemove VM_LOCKED before remap_pfn range from device drivers and get rid of\nVM_SHM.\n\nremap_pfn_range() already sets VM_IO.

(If the process were later to fault on this\n orphaned entry, it would hit the same BUG from migration_entry_wait.)\n\n This could be fixed by locking anon_vma in copy_one_pte, but we\u0027d rather\n not. There\u0027s no such problem with file pages, because vma_prio_tree_add\n adds child vma after parent vma, and the page table locking at each end is\n enough to serialize. Follow that example with anon_vma: add new vmas to the\n tail instead of the head.\n\n (There\u0027s no corresponding problem when inserting migration entries,\n because a missed pte will leave the page count and mapcount high, which is\n allowed for. And there\u0027s no corresponding problem when migrating via swap,\n because a leftover swap entry will be correctly faulted.
