The changelog for that patch was:\n\n The shrink_zone() logic can, under some circumstances, cause far too many\n pages to be reclaimed. Say, we\u0027re scanning at high priority and suddenly\n hit a large number of reclaimable pages on the LRU.\n\n Change things so we bale out when SWAP_CLUSTER_MAX pages have been\n reclaimed.\n\nProblem is, this change caused significant imbalance in inter-zone scan\nbalancing by truncating scans of larger zones.\n\nSuppose, for example, ZONE_HIGHMEM is 10x the size of ZONE_NORMAL. The zone\nbalancing algorithm would require that if we\u0027re scanning 100 pages of\nZONE_HIGHMEM, we should scan 10 pages of ZONE_NORMAL. But this logic will\ncause the scanning of ZONE_HIGHMEM to bale out after only 32 pages are\nreclaimed. Thus effectively causing smaller zones to be scanned relatively\nharder than large ones.\n\nNow I need to remember what the workload was which caused me to write this\npatch originally, then fix it up in a different way...\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "41e9b63b35b52cf918a4ffdb8d77862ab824aa8b", "tree": "472ef8bb097f4e090f5fc95100acdbc77f515087", "parents": [ "9617d95e6e9ffd883cf90a89724fe60d7ab22f9a" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Fri Jan 06 00:11:13 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:27 2006 -0800" }, "message": "[PATCH] mm: pfault optimisation\n\nThis atomic operation is superfluous: the pte will be added with the\nreferenced bit set, and the page will be referenced through this mapping after\nthe page fault handler returns anyway.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9617d95e6e9ffd883cf90a89724fe60d7ab22f9a", "tree": "67d555d34d931bd253fbc4959ffdb1e5b904f2b0", "parents": [ "224abf92b2f439a9030f21d2926ec8047d1ffcdb" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Fri Jan 06 00:11:12 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:27 2006 -0800" }, "message": "[PATCH] mm: rmap optimisation\n\nOptimise rmap functions by minimising atomic operations when we know there\nwill be no concurrent modifications.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "224abf92b2f439a9030f21d2926ec8047d1ffcdb", "tree": "e45074383aea04ef8b3b8d2cc04a3b34959f9e65", "parents": [ "9328b8faae922e52073785ed6c1eaa8565648a0e" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Fri Jan 06 00:11:11 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:26 2006 -0800" }, "message": "[PATCH] mm: bad_page optimisation\n\nCut down size slightly by not passing bad_page the function name (it should be\nable to be determined by dump_stack()).

Add a pair of functions to set/clear write access on huge ptes. The\n writable check in make_huge_pte is moved out to the caller for use by COW\n later.\n\n2. Hugetlb copy-on-write requires special case handling in the following\n situations:\n\n - copy_hugetlb_page_range() - Copied pages must be write protected so\n a COW fault will be triggered (if necessary) if those pages are written\n to.\n\n - find_or_alloc_huge_page() - Only MAP_SHARED pages are added to the\n page cache.

Current\nimplementation supports only shmfs/tmpfs and other filesystems return\n-ENOSYS.\n\n\"Some app allocates large tmpfs files, then when some task quits and some\nclient disconnect, some memory can be released. However the only way to\nrelease tmpfs-swap is to MADV_REMOVE\". - Andrea Arcangeli\n\nDatabases want to use this feature to drop a section of their bufferpool\n(shared memory segments) - without writing back to disk/swap space.\n\nThis feature is also useful for supporting hot-plug memory on UML.\n\nConcerns raised by Andrew Morton:\n\n- \"We have no plan for holepunching! If we _do_ have such a plan (or\n might in the future) then what would the API look like? I think\n sys_holepunch(fd, start, len), so we should start out with that.\"\n\n- Using madvise is very weird, because people will ask \"why do I need to\n mmap my file before I can stick a hole in it?\"\n\n- None of the other madvise operations call into the filesystem in this\n manner. A broad question is: is this capability an MM operation or a\n filesytem operation? truncate, for example, is a filesystem operation\n which sometimes has MM side-effects. madvise is an mm operation and with\n this patch, it gains FS side-effects, only they\u0027re really, really\n significant ones.\"\n\nComments:\n\n- Andrea suggested the fs operation too but then it\u0027s more efficient to\n have it as a mm operation with fs side effects, because they don\u0027t\n immediatly know fd and physical offset of the range. It\u0027s possible to\n fixup in userland and to use the fs operation but it\u0027s more expensive,\n the vmas are already in the kernel and we can use them.\n\nShort term plan \u0026 Future Direction:\n\n- We seem to need this interface only for shmfs/tmpfs files in the short\n term. We have to add hooks into the filesystem for correctness and\n completeness. This is what this patch does.\n\n- In the future, plan is to support both fs and mmap apis also. This\n also involves (other) filesystem specific functions to be implemented.\n\n- Current patch doesn\u0027t support VM_NONLINEAR - which can be addressed in\n the future.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d7339071f6a8b50101d7ba327926b770f22d5d8b", "tree": "051234ada89be22abb9ebbe4a541b16ade3bc2ff", "parents": [ "900b2b463dc6e65ec474d6880412c63c25b3aea9" ], "author": { "name": "Hans Reiser", "email": "reiser@namesys.com", "time": "Fri Jan 06 00:10:36 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:22 2006 -0800" }, "message": "[PATCH] reiser4: vfs: add truncate_inode_pages_range()\n\nThis patch makes truncate_inode_pages_range from truncate_inode_pages.\ntruncate_inode_pages became a one-liner call to truncate_inode_pages_range.\n\nReiser4 needs truncate_inode_pages_ranges because it tries to keep\ncorrespondence between existences of metadata pointing to data pages and pages\nto which those metadata point to.

Both was ruled out at this point because it was in early\n2.4 when VM is still quite shakey and had bad troubles even\ndealing with one DMA zone. We settled on the 16MB DMA zone mainly\nbecause we worried about older soundcards and the floppy.\n\nBut this has always caused problems since then because\ndevice drivers had trouble getting enough DMA able memory. These days\nthe VM works much better and the wide use of NUMA has proven\nit can deal with many zones successfully.\n\nSo this patch adds both zones.\n\nThis helps drivers who need a lot of memory below 4GB because\ntheir hardware is not accessing more (graphic drivers - proprietary\nand free ones, video frame buffer drivers, sound drivers etc.).\nPreviously they could only use IOMMU+16MB GFP_DMA, which\nwas not enough memory.\n\nAnother common problem is that hardware who has full memory\naddressing for \u003e4GB misses it for some control structures in memory\n(like transmit rings or other metadata). They tended to allocate memory\nin the 16MB GFP_DMA or the IOMMU/swiotlb then using pci_alloc_consistent,\nbut that can tie up a lot of precious 16MB GFPDMA/IOMMU/swiotlb memory\n(even on AMD systems the IOMMU tends to be quite small) especially if you have\nmany devices. With the new zone pci_alloc_consistent can just put\nthis stuff into memory below 4GB which works better.\n\nOne argument was still if the zone should be 4GB or 2GB. The main\nmotivation for 2GB would be an unnamed not so unpopular hardware\nraid controller (mostly found in older machines from a particular four letter\ncompany) who has a strange 2GB restriction in firmware. But\nthat one works ok with swiotlb/IOMMU anyways, so it doesn\u0027t really\nneed GFP_DMA32. I chose 4GB to be compatible with IA64 and because\nit seems to be the most common restriction.\n\nThe new zone is so far added only for x86-64.\n\nFor other architectures who don\u0027t set up this\nnew zone nothing changes. Architectures can set a compatibility\ndefine in Kconfig CONFIG_DMA_IS_DMA32 that will define GFP_DMA32\nas GFP_DMA. Otherwise it\u0027s a nop because on 32bit architectures\nit\u0027s normally not needed because GFP_NORMAL (\u003d0) is DMA able\nenough.\n\nOne problem is still that GFP_DMA means different things on different\narchitectures. e.g. some drivers used to have #ifdef ia64 use GFP_DMA\n(trusting it to be 4GB) #elif __x86_64__ (use other hacks like\nthe swiotlb because 16MB is not enough) ... . This was quite\nugly and is now obsolete.\n\nThese should be now converted to use GFP_DMA32 unconditionally. I haven\u0027t done\nthis yet. Or best only use pci_alloc_consistent/dma_alloc_coherent\nwhich will use GFP_DMA32 transparently.\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "50c85a19e7b3928b5b5188524c44ffcbacdd4e35", "tree": "a886792eba2e11615c3846bc6b1c77c41ce6dda0", "parents": [ "065d41cb269e9debb18c6d5052e4de1088ae3d8f" ], "author": { "name": "Christoph Lameter", "email": "clameter@engr.sgi.com", "time": "Sun Nov 13 16:06:47 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Nov 13 18:14:12 2005 -0800" }, "message": "[PATCH] slab: remove alloc_pages() calls\n\nThe slab allocator never uses alloc_pages since kmem_getpages() is always\ncalled with a valid nodeid.
