This may be improved by using\nhighmem for saving the contents of saveable highmem pages.\n\nNamely, during the suspend phase of the suspend-resume cycle we try to\nallocate as many free highmem pages as there are saveable highmem pages.\nIf there are not enough highmem image pages to store the contents of all of\nthe saveable highmem pages, some of them will be stored in the \"normal\"\nmemory. Next, we allocate as many free \"normal\" pages as needed to store\nthe (remaining) image data. We use a memory bitmap to mark the allocated\nfree pages (ie. highmem as well as \"normal\" image pages).\n\nNow, we use another memory bitmap to mark all of the saveable pages\n(highmem as well as \"normal\") and the contents of the saveable pages are\ncopied into the image pages. Then, the second bitmap is used to save the\npfns corresponding to the saveable pages and the first one is used to save\ntheir data.\n\nDuring the resume phase the pfns of the pages that were saveable during the\nsuspend are loaded from the image and used to mark the \"unsafe\" page\nframes. Next, we try to allocate as many free highmem page frames as to\nload all of the image data that had been in the highmem before the suspend\nand we allocate so many free \"normal\" page frames that the total number of\nallocated free pages (highmem and \"normal\") is equal to the size of the\nimage. While doing this we have to make sure that there will be some extra\nfree \"normal\" and \"safe\" page frames for two lists of PBEs constructed\nlater.\n\nNow, the image data are loaded, if possible, into their \"original\" page\nframes. The image data that cannot be written into their \"original\" page\nframes are loaded into \"safe\" page frames and their \"original\" kernel\nvirtual addresses, as well as the addresses of the \"safe\" pages containing\ntheir copies, are stored in one of two lists of PBEs.\n\nOne list of PBEs is for the copies of \"normal\" suspend pages (ie. \"normal\"\npages that were saveable during the suspend) and it is used in the same way\nas previously (ie. by the architecture-dependent parts of swsusp). The\nother list of PBEs is for the copies of highmem suspend pages. The pages\nin this list are restored (in a reversible way) right before the\narch-dependent code is called.\n\nSigned-off-by: Rafael J.

From the swsusp\u0027s point of view (1) is not a problem,\n because it is already taken care of by the swap-handling code, but (2) has\n to be taken into consideration.\n\nIn principle the location of a swap file\u0027s header may be determined with the\nhelp of appropriate filesystem driver. Unfortunately, however, it requires\nthe filesystem holding the swap file to be mounted, and if this filesystem is\njournaled, it cannot be mounted during a resume from disk. For this reason we\nneed some other means by which swap areas can be identified.\n\nFor example, to identify a swap area we can use the partition that holds the\narea and the offset from the beginning of this partition at which the swap\nheader is located.\n\nThe following patch allows swsusp to identify swap areas this way.

The urgency for the token is based on the number of times\na task is required to swap-in pages. Accordingly, the priority of a task is\nincremented if it has been badly affected due to swap-outs. To ensure that\nthe token doesnt bounce around rapidly, the token holders are given a priority\nboost. The priority of tasks is also decremented, if their rate of swap-in\u0027s\nkeeps reducing. This way, the condition to check whether to pre-empt the swap\ntoken, is a matter of comparing two task\u0027s priority fields.\n\n[akpm@osdl.org: cleanups]\nSigned-off-by: Ashwin Chaugule \u003cashwin.chaugule@celunite.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9db73724453a9350e1c22dbe732d427e2939a5c9", "tree": "15e3ead6413ae97398a54292acc199bee0864d42", "parents": [ "4c1ac1b49122b805adfa4efc620592f68dccf5db", "e62438630ca37539c8cc1553710bbfaa3cf960a7" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Dec 05 17:01:28 2006 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@warthog.cambridge.redhat.com", "time": "Tue Dec 05 17:01:28 2006 +0000" }, "message": "Merge branch \u0027master\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6\n\nConflicts:\n\n\tdrivers/ata/libata-scsi.c\n\tinclude/linux/libata.h\n\nFuther merge of Linus\u0027s head and compilation fixups.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "4c1ac1b49122b805adfa4efc620592f68dccf5db", "tree": "87557f4bc2fd4fe65b7570489c2f610c45c0adcd", "parents": [ "c4028958b6ecad064b1a6303a6a5906d4fe48d73", "d916faace3efc0bf19fe9a615a1ab8fa1a24cd93" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Dec 05 14:37:56 2006 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@warthog.cambridge.redhat.com", "time": "Tue Dec 05 14:37:56 2006 +0000" }, "message": "Merge branch \u0027master\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6\n\nConflicts:\n\n\tdrivers/infiniband/core/iwcm.c\n\tdrivers/net/chelsio/cxgb2.c\n\tdrivers/net/wireless/bcm43xx/bcm43xx_main.c\n\tdrivers/net/wireless/prism54/islpci_eth.c\n\tdrivers/usb/core/hub.h\n\tdrivers/usb/input/hid-core.c\n\tnet/core/netpoll.c\n\nFix up merge failures with Linus\u0027s head and fix new compilation failures.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "a1f8e7f7fb9d7e2cbcb53170edca7c0ac4680697", "tree": "2d1190c0099291d56a9c986f16bec17df2f6768b", "parents": [ "b07e4ecd4d380ad697c54d729cb653d027077c99" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu Oct 19 16:08:53 2006 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Dec 04 02:00:29 2006 -0500" }, "message": "[PATCH] severing skbuff.h -\u003e highmem.h\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "f6a570333e554b48ad589e7137c77c57809eee81", "tree": "68dd6d5c8fe537a19a84a4189202f5cf70925c17", "parents": [ "2b5f6dcce5bf94b9b119e9ed8d537098ec61c3d2" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Oct 18 01:47:25 2006 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Dec 04 02:00:22 2006 -0500" }, "message": "[PATCH] severing module.h-\u003esched.h\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "17c157c889f4b07258af6bfec9e4e9dcf3c00178", "tree": "f17be049a40b5742ca7e67094d6a7063146568d5", "parents": [ "81878d27fdd297a33f3cfcf29483fe1abaf26dec" ], "author": { "name": "Thomas Graf", "email": "tgraf@suug.ch", "time": "Tue Nov 14 19:46:02 2006 -0800" }, "committer": { "name": "David S.

The proc interface\nto sysctl does not have that problem, as names are not densely allocated.\n\nBy not terminating a sysctl table until I have neither a ctl_name nor a\nprocname, it becomes simple to add sysctl entries that don\u0027t show up in the\nbinary sysctl interface.
