This\n is currently the only instance thereof. However, if we found more uses for\n this concept, and introduced any ambiguity as to whether a mempolicy was\n context free or not, we could add another internal mode flag to identify\n context free mempolicies.

In other areas, further inspection reveals that I botched the\nunref for interleave policies.\n\nA separate patch, suitable for upstream/stable trees, fixes up the known\nerrors in the previous attempt to fix reference counting.\n\nThis patch reworks the memory policy referencing counting and, one hopes,\nsimplifies the code. Maybe I\u0027ll get it right this time.\n\nSee the update to the numa_memory_policy.txt document for a discussion of\nmemory policy reference counting that motivates this patch.\n\nSummary:\n\nLookup of mempolicy, based on (vma, address) need only add a reference for\nshared policy, and we need only unref the policy when finished for shared\npolicies. So, this patch backs out all of the unneeded extra reference\ncounting added by my previous attempt. It then unrefs only shared policies\nwhen we\u0027re finished with them, using the mpol_cond_put() [conditional put]\nhelper function introduced by this patch.\n\nNote that shmem_swapin() calls read_swap_cache_async() with a dummy vma\ncontaining just the policy. read_swap_cache_async() can call alloc_page_vma()\nmultiple times, so we can\u0027t let alloc_page_vma() unref the shared policy in\nthis case. To avoid this, we make a copy of any non-null shared policy and\nremove the MPOL_F_SHARED flag from the copy. This copy occurs before reading\na page [or multiple pages] from swap, so the overhead should not be an issue\nhere.\n\nI introduced a new static inline function \"mpol_cond_copy()\" to copy the\nshared policy to an on-stack policy and remove the flags that would require a\nconditional free. The current implementation of mpol_cond_copy() assumes that\nthe struct mempolicy contains no pointers to dynamically allocated structures\nthat must be duplicated or reference counted during copy.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a6020ed759404372e8be2b276e85e51735472cc9", "tree": "1fb0a346909dcc9d3b916671001af87b17931ddd", "parents": [ "aab0b1029f0843756b68e0ed3ca983685bf43ed6" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:14 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: document {set|get}_policy() vm_ops APIs\n\nDocument mempolicy return value reference semantics assumed by the rest of the\nmempolicy code for the set_ and get_policy vm_ops in \u003clinux/mm.h\u003e--where the\nprototypes are defined--to inform any future mempolicy vm_op writers what the\nrest of the subsystem expects of them.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "aab0b1029f0843756b68e0ed3ca983685bf43ed6", "tree": "95a0546c908a1c7a3bf1353f433ff1464faf68db", "parents": [ "45c4745af381851b0406d8e4db99e62e265691c2" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:13 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: mark shared policies for unref\n\nAs part of yet another rework of mempolicy reference counting, we want to be\nable to identify shared policies efficiently, because they have an extra ref\ntaken on lookup that needs to be removed when we\u0027re finished using the policy.\n\n Note: the extra ref is required because the policies are\n shared between tasks/processes and can be changed/freed\n by one task while another task is using them--e.g., for\n page allocation.\n\nBuilding on David Rientjes mempolicy \"mode flags\" enhancement, this patch\nindicates a \"shared\" policy by setting a new MPOL_F_SHARED flag in the flags\nmember of the struct mempolicy added by David.

The presence of the two entries is contingent upon CONFIG_HUGETLB_PAGE\nbeing enabled.\n\n[akpm@linux-foundation.org: reduced ifdeffery]\nSigned-off-by: Adam Litke \u003cagl@us.ibm.com\u003e\nSigned-off-by: Eric Munson \u003cebmunson@us.ibm.com\u003e\nTested-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nReviewed-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a08cb629f546d1cecebe955392197f226e58dbe1", "tree": "1cbab3071f6d35a0f58abc0ad3b05641ed41df6b", "parents": [ "70688e4dd1647f0ceb502bbd5964fa344c5eb411" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Mon Apr 28 02:13:03 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:23 2008 -0700" }, "message": "s390: implement pte special bit\n\nConvert XIP to support non-struct page backed memory, using VM_MIXEDMAP for\nthe user mappings.\n\nThis requires the get_xip_page API to be changed to an address based one.\nImprove the API layering a little bit too, while we\u0027re here.\n\nThis is required in order to support XIP filesystems on memory that isn\u0027t\nbacked with struct page (but memory with struct page is still supported too).\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "70688e4dd1647f0ceb502bbd5964fa344c5eb411", "tree": "e0bd8c3b4b6050c067a453d800c2e87948d1abaf", "parents": [ "30afcb4bd2762fa4b87b17ada9500aa46dc10b1b" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Mon Apr 28 02:13:02 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:23 2008 -0700" }, "message": "xip: support non-struct page backed memory\n\nConvert XIP to support non-struct page backed memory, using VM_MIXEDMAP for\nthe user mappings.\n\nThis requires the get_xip_page API to be changed to an address based one.\nImprove the API layering a little bit too, while we\u0027re here.\n\nThis is required in order to support XIP filesystems on memory that isn\u0027t\nbacked with struct page (but memory with struct page is still supported too).\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "30afcb4bd2762fa4b87b17ada9500aa46dc10b1b", "tree": "0920f491a37683a8784c146270b98f82a7e0aa2c", "parents": [ "423bad600443c590f34ed7ce357591f76f48f137" ], "author": { "name": "Jared Hulbert", "email": "jaredeh@gmail.com", "time": "Mon Apr 28 02:13:02 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:23 2008 -0700" }, "message": "return pfn from direct_access, for XIP\n\nAlter the block device -\u003edirect_access() API to work with the new\nget_xip_mem() API (that requires both kaddr and pfn are returned).\n\nSome architectures will not do the right thing in their virt_to_page() for use\nby XIP (to translate from the kernel virtual address returned by\ndirect_access(), to a user mappable pfn in XIP\u0027s page fault handler.\n\nHowever, we can\u0027t switch it to just return the pfn and not the kaddr, because\nwe have no good way to get a kva from a pfn, and XIP requires the kva for its\nread(2) and write(2) handlers.

We do\nnot want architectures to know or care about vm_normal_page itself, and\nwe definitely don\u0027t want them being able to invent something new there\nout of sight of mm/ code. If we made vm_normal_page an arch function, then\nwe have to make vm_insert_mixed (next patch) an arch function too. So I\ndon\u0027t think moving it to arch code fundamentally improves any abstractions,\nwhile it does practically make the code more difficult to follow, for both\nmm and arch developers, and easier to misuse.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b379d790197cdf8a95fb67507d75a24ac0a1678d", "tree": "8ea36c9a0766aca3cfd69cd33aa8a5d2ca8dd2d4", "parents": [ "214e471ff99064726b2d8af3aa0e24a73c775531" ], "author": { "name": "Jared Hulbert", "email": "jaredeh@gmail.com", "time": "Mon Apr 28 02:12:58 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:22 2008 -0700" }, "message": "mm: introduce VM_MIXEDMAP\n\nThis series introduces some important infrastructure work. The overall result\nis that:\n\n1. We now support XIP backed filesystems using memory that have no\n struct page allocated to them. And patches 6 and 7 actually implement\n this for s390.\n\n This is pretty important in a number of cases. As far as I understand,\n in the case of virtualisation (eg. s390), each guest may mount a\n readonly copy of the same filesystem (eg. the distro). Currently,\n guests need to allocate struct pages for this image. So if you have\n 100 guests, you already need to allocate more memory for the struct\n pages than the size of the image. I think. (Carsten?)\n\n For other (eg. embedded) systems, you may have a very large non-\n volatile filesystem. If you have to have struct pages for this, then\n your RAM consumption will go up proportionally to fs size. Even\n though it is just a small proportion, the RAM can be much more costly\n eg in terms of power, so every KB less that Linux uses makes it more\n attractive to a lot of these guys.\n\n2. VM_MIXEDMAP allows us to support mappings where you actually do want\n to refcount _some_ pages in the mapping, but not others, and support\n COW on arbitrary (non-linear) mappings. Jared needs this for his NVRAM\n filesystem in progress. Future iterations of this filesystem will\n most likely want to migrate pages between pagecache and XIP backing,\n which is where the requirement for mixed (some refcounted, some not)\n comes from.\n\n3. pte_special also has a peripheral usage that I need for my lockless\n get_user_pages patch. That was shown to speed up \"oltp\" on db2 by\n 10% on a 2 socket system, which is kind of significant because they\n scrounge for months to try to find 0.1% improvement on these\n workloads. I\u0027m hoping we might finally be faster than AIX on\n pSeries with this :). My reference to lockless get_user_pages is not\n meant to justify this patchset (which doesn\u0027t include lockless gup),\n but just to show that pte_special is not some s390 specific thing that\n should be hidden in arch code or xip code: I definitely want to use it\n on at least x86 and powerpc as well.\n\nThis patch:\n\nIntroduce a new type of mapping, VM_MIXEDMAP. This is unlike VM_PFNMAP in\nthat it can support COW mappings of arbitrary ranges including ranges without\nstruct page *and* ranges with a struct page that we actually want to refcount\n(PFNMAP can only support COW in those cases where the un-COW-ed translations\nare mapped linearly in the virtual address, and can only support non\nrefcounted ranges).\n\nVM_MIXEDMAP achieves this by refcounting all pfn_valid pages, and not\nrefcounting !pfn_valid pages (which is not an option for VM_PFNMAP, because it\nneeds to avoid refcounting pfn_valid pages eg. for /dev/mem mappings).\n\nSigned-off-by: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e20b8cca760ed2a6abcfe37ef56f2306790db648", "tree": "85e5610364f73da193ee781be61710fddfbe045f", "parents": [ "97965478a66fbdf0f4ad5e4ecc4828f0cb548a45" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Mon Apr 28 02:12:55 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:22 2008 -0700" }, "message": "PAGEFLAGS_EXTENDED and separate page flags for Head and Tail\n\nHaving separate page flags for the head and the tail of a compound page allows\nthe compiler to use bitops instead of operations on a word to check for a tail\npage.
