There\u0027s\nactually a library function in include/linux/highmem.h that does exactly\nthat, but it\u0027s confusingly named memclear_highpage_flush(), which is\ndescriptive of *how* it does the work rather than what the *purpose* is.\nSo this patchset renames the function to zero_user_page(), and calls it\nfrom the various places that currently open code it.\n\nThis first patch introduces the new function call, and converts all the\ncore kernel callsites, both the open-coded ones and the old\nmemclear_highpage_flush() ones. Following this patch is a series of\nconversions for each file system individually, per AKPM, and finally a\npatch deprecating the old call. The diffstat below shows the entire\npatchset.\n\n[akpm@linux-foundation.org: fix a few things]\nSigned-off-by: Nate Diller \u003cnate.diller@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e63340ae6b6205fef26b40a75673d1c9c0c8bb90", "tree": "8d3212705515edec73c3936bb9e23c71d34a7b41", "parents": [ "04c9167f91e309c9c4ea982992aa08e83b2eb42e" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Tue May 08 00:28:08 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:07 2007 -0700" }, "message": "header cleaning: don\u0027t include smp_lock.h when not used\n\nRemove includes of \u003clinux/smp_lock.h\u003e where it is not used/needed.\nSuggested by Al Viro.\n\nBuilds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,\nsparc64, and arm (all 59 defconfigs).\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7e4c3690b07f04b1942c39db358a5c8a72831daa", "tree": "70d8773f612ed3df02c738b678edef64dd5ddaf7", "parents": [ "3e9f45bd18191bbd05468b19b7064b8da8262aba" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Tue May 08 00:23:27 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:14:57 2007 -0700" }, "message": "block_write_full_page(): report ENOSPC\n\nblock_write_full_page() forgot to propagate ENPSOC into the address_space.\n\nCc: Guillaume Chazarain \u003cguichaz@yahoo.fr\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "50953fe9e00ebbeffa032a565ab2f08312d51a87", "tree": "9f95f56f0b51600959a76cd88ce17f6e9c7a98a3", "parents": [ "4b1d89290b62bb2db476c94c82cf7442aab440c8" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Sun May 06 14:50:16 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 07 12:12:57 2007 -0700" }, "message": "slab allocators: Remove SLAB_DEBUG_INITIAL flag\n\nI have never seen a use of SLAB_DEBUG_INITIAL.

On page write-back clean all the\nPTE dirty bits and write protect them once again.\n\nThe implementation is a tad harder, mainly because the default\nbacking_dev_info capabilities were too loosely maintained. Hence it is not\nenough to test the backing_dev_info for cap_account_dirty.\n\nThe current heuristic is as follows, a VMA is eligible when:\n - its shared writeable\n (vm_flags \u0026 (VM_WRITE|VM_SHARED)) \u003d\u003d (VM_WRITE|VM_SHARED)\n - it is not a \u0027special\u0027 mapping\n (vm_flags \u0026 (VM_PFNMAP|VM_INSERTPAGE)) \u003d\u003d 0\n - the backing_dev_info is cap_account_dirty\n mapping_cap_account_dirty(vma-\u003evm_file-\u003ef_mapping)\n - f_op-\u003emmap() didn\u0027t change the default page protection\n\nPage from remap_pfn_range() are explicitly excluded because their COW\nsemantics are already horrid enough (see vm_normal_page() in do_wp_page()) and\nbecause they don\u0027t have a backing store anyway.\n\nmprotect() is taught about the new behaviour as well. However it overrides\nthe last condition.\n\nCleaning the pages on write-back is done with page_mkclean() a new rmap call.\nIt can be called on any page, but is currently only implemented for mapped\npages, if the page is found the be of a VMA that accounts dirty pages it will\nalso wrprotect the PTE.\n\nFinally, in fs/buffers.c:try_to_free_buffers(); remove clear_page_dirty() from\nunder -\u003eprivate_lock. This seems to be safe, since -\u003eprivate_lock is used to\nserialize access to the buffers, not the page itself. This is needed because\nclear_page_dirty() will call into page_mkclean() and would thereby violate\nlocking order.\n\n[dhowells@redhat.com: Provide a page_mkclean() implementation for NOMMU]\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0e1dfc66b6ec94984a4778132147a8aa36461d58", "tree": "225a8e044e021a5a337704bc1f5ea862a5f75375", "parents": [ "a268cefebceeb2046dfdfa301f041c2468536852" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Sun Jul 30 03:03:28 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 31 13:28:38 2006 -0700" }, "message": "[PATCH] invalidate_bdev() speedup\n\nWe can immediately bail from invalidate_bdev() if the blockdev has no\npagecache.\n\nThis solves the huge IPI storms which hald is causing on the big ia64\nmachines when it polls CDROM drives.\n\nAcked-by: Jes Sorensen \u003cjes@sgi.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "22a3e233ca08a2ddc949ba1ae8f6e16ec7ef1a13", "tree": "7ef158ba2c30e0dde2dc103d1904fae243759a6b", "parents": [ "39302175c26d74be35715c05a0f342c9e64c21bf", "6ab3d5624e172c553004ecc862bfeac16d9d68b7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 30 15:39:30 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 30 15:39:30 2006 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/bunk/trivial\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/bunk/trivial:\n Remove obsolete #include \u003clinux/config.h\u003e\n remove obsolete swsusp_encrypt\n arch/arm26/Kconfig typos\n Documentation/IPMI typos\n Kconfig: Typos in net/sched/Kconfig\n v9fs: do not include linux/version.h\n Documentation/DocBook/mtdnand.tmpl: typo fixes\n typo fixes: specfic -\u003e specific\n typo fixes in Documentation/networking/pktgen.txt\n typo fixes: occuring -\u003e occurring\n typo fixes: infomation -\u003e information\n typo fixes: disadvantadge -\u003e disadvantage\n typo fixes: aquire -\u003e acquire\n typo fixes: mecanism -\u003e mechanism\n typo fixes: bandwith -\u003e bandwidth\n fix a typo in the RTC_CLASS help text\n smb is no longer maintained\n\nManually merged trivial conflict in arch/um/kernel/vmlinux.lds.S\n" }, { "commit": "b1e7a8fd854d2f895730e82137400012b509650e", "tree": "9fba87ff6b0146ebd4ee5bc7d5f0c8b037dbb3ad", "parents": [ "df849a1529c106f7460e51479ca78fe07b07dc8c" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Fri Jun 30 01:55:39 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 30 11:25:35 2006 -0700" }, "message": "[PATCH] zoned vm counters: conversion of nr_dirty to per zone counter\n\nThis makes nr_dirty a per zone counter.

(previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners.

It calls\nthe get_block() callback with \"create \u003d 1\" and if that succeeds it\nimmediately clears buffer_new on the just allocated buffer (which has\nbuffer_new set).\n\nThe bug is that if an error occurs and get_block() returns !\u003d 0, we break\nfrom this loop and go into recovery code. This code has this comment:\n\n/* Error case: */\n/*\n * Zero out any newly allocated blocks to avoid exposing stale\n * data.
