The\nzoneref that is returned corresponds to the the next zone that is to be\nscanned, not the current one. It was intended to be treated as an opaque\nlist.\n\nWhen the page allocator is scanning a zonelist, it marks elements in the\nzonelist corresponding to zones that are temporarily full. As the\nzonelist is being updated, it uses the cursor here;\n\n if (NUMA_BUILD)\n zlc_mark_zone_full(zonelist, z);\n\nThis is intended to prevent rescanning in the near future but the zoneref\ncursor does not correspond to the zone that has been found to be full.\nThis is an easy misunderstanding to make so this patch corrects the\nproblem by changing zoneref cursor to be the current zone being scanned\ninstead of the next one.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[2.6.26.x]\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "dea420ce0e2973e8ef1fd11fde6804c8d03a82ad", "tree": "b5dcf39a9d36693eac02813db2b603500e545e59", "parents": [ "665020c35e89a9e0643e21561e4f8f967f4f2c4b" ], "author": { "name": "Hiroshi DOYU", "email": "Hiroshi.DOYU@nokia.com", "time": "Sat Sep 13 02:33:07 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Sep 13 14:41:50 2008 -0700" }, "message": "include/linux/ioport.h: add missing macro argument for devm_release_* family\n\nakpm: these have no callers at this time, but they shall soon, so let\u0027s\nget them right.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Hiroshi DOYU \u003cHiroshi.DOYU@nokia.com\u003e\nCc: Tony Lindgren \u003ctony@atomide.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "97b697a11b07e2ebfa69c488132596cc5eb24119", "tree": "942176291faf6ab0dff6297708ca8b98f6e2e8c1", "parents": [ "99580664aa83ca04bb52988d504a4195b41833b0" ], "author": { "name": "Taisuke Yamada", "email": "tai@rakugaki.org", "time": "Sat Sep 13 16:46:15 2008 -0400" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Sat Sep 13 16:46:15 2008 -0400" }, "message": "[libata] LBA28/LBA48 off-by-one bug in ata.h\n\nI recently bought 3 HGST P7K500-series 500GB SATA drives and\nhad trouble accessing the block right on the LBA28-LBA48 border.\nHere\u0027s how it fails (same for all 3 drives):\n\n # dd if\u003d/dev/sdc bs\u003d512 count\u003d1 skip\u003d268435455 \u003e /dev/null\n dd: reading `/dev/sdc\u0027: Input/output error\n 0+0 records in\n 0+0 records out\n 0 bytes (0 B) copied, 0.288033 seconds, 0.0 kB/s\n # dmesg\n ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0\n ata1.00: BMDMA stat 0x25\n ata1.00: cmd c8/00:08:f8:ff:ff/00:00:00:00:00/ef tag 0 dma 4096 in\n res 51/04:08:f8:ff:ff/00:00:00:00:00/ef Emask 0x1 (device error)\n ata1.00: status: { DRDY ERR }\n ata1.00: error: { ABRT }\n ata1.00: configured for UDMA/33\n ata1: EH complete\n ...\n\nAfter some investigations, it turned out this seems to be caused\nby misinterpretation of the ATA specification on LBA28 access.\nFollowing part is the code in question:\n\n \u003d\u003d\u003d include/linux/ata.h \u003d\u003d\u003d\n static inline int lba_28_ok(u64 block, u32 n_block)\n {\n /* check the ending block number */\n return ((block + n_block - 1) \u003c ((u64)1 \u003c\u003c 28)) \u0026\u0026 (n_block \u003c\u003d 256);\n }\n\nHGST drive (sometimes) fails with LBA28 access of {block \u003d 0xfffffff,\nn_block \u003d 1}, and this behavior seems to be comformant. Other drives,\nincluding other HGST drives are not that strict, through.\n\n\u003eFrom the ATA specification:\n(http://www.t13.org/Documents/UploadedDocuments/project/d1410r3b-ATA-ATAPI-6.pdf)\n\n 8.15.29 Word (61:60): Total number of user addressable sectors\n This field contains a value that is one greater than the total number\n of user addressable sectors (see 6.2). The maximum value that shall\n be placed in this field is 0FFFFFFFh.\n\nSo the driver shouldn\u0027t use the value of 0xfffffff for LBA28 request\nas this exceeds maximum user addressable sector. The logical maximum\nvalue for LBA28 is 0xffffffe.\n\nThe obvious fix is to cut \"- 1\" part, and the patch attached just do\nthat. I\u0027ve been using the patched kernel for about a month now, and\nthe same fix is also floating on the net for some time. So I believe\nthis fix works reliably.\n\nJust FYI, many Windows/Intel platform users also seems to be struck\nby this, and HGST has issued a note pointing to Intel ICH8/9 driver.\n\n \"28-bit LBA command is being used to access LBAs 29-bits in length\"\nhttp://www.hitachigst.com/hddt/knowtree.nsf/cffe836ed7c12018862565b000530c74/b531b8bce8745fb78825740f00580e23\n\nAlso, *BSDs seems to have similar fix included sometime around ~2004,\nthrough I have not checked out exact portion of the code.\n\nSigned-off-by: Taisuke Yamada \u003ctai@rakugaki.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "2dc75d3c3b49c64fd26b4832a7efb75546cb3fc5", "tree": "908ae81851ca06d46a680d8e6c33afdfb292c131", "parents": [ "adee14b2e1557d0a8559f29681732d05a89dfc35" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu Sep 11 14:20:23 2008 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu Sep 11 14:20:23 2008 +0200" }, "message": "block: disable sysfs parts of the disk command filter\n\nWe still have life time issues with the sysfs command filter kobject,\nso disable it for 2.6.27 release.

b27f03d4bdc145a09fb7b0c0e004b29f1ee555fa. The suspected\nreason for the problem is that signal_struct maintains it\u0027s own utime and\nstime (of exited tasks), these are not updated using the new task_utime()\nroutine, hence sig-\u003eutime can go backwards and cause the same problem\nto occur (sig-\u003eutime, adds tsk-\u003eutime and not task_utime()). This patch\nfixes the problem\n\nTODO: using max(task-\u003eprev_utime, derived utime) works for now, but a more\ngeneric solution is to implement cputime_max() and use the cputime_gt()\nfunction for comparison.\n\nReported-by: spencer@bluehost.com\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "afbc8d8e72daa5a5faf6a0242186bdfcc42b2427", "tree": "8d3c699c56daffdaa1d18507f23044fb7b9fd36f", "parents": [ "076c7f4c6c55c37975c8e04ae6827267794d5d2e" ], "author": { "name": "Khem Raj", "email": "raj.khem@gmail.com", "time": "Thu Sep 04 23:11:01 2008 -0700" }, "committer": { "name": "David Woodhouse", "email": "David.Woodhouse@intel.com", "time": "Fri Sep 05 15:44:31 2008 +0100" }, "message": "Fix conditional export of kvh.h and a.out.h to userspace.\n\nSome architectures have moved the asm/ into arch/ and some have not.\nThis patch checks for a.out.h and kvh.h in both places before exporting\nthe corresponding file from linux/\n\n[dwmw2: simplified a little]\nSigned-off-by: Khem Raj \u003craj.khem@gmail.com\u003e\nSigned-off-by: David Woodhouse \u003cDavid.Woodhouse@intel.com\u003e\n" }, { "commit": "7c1e76897492d92b6a1c2d6892494d39ded9680c", "tree": "ea04e1be252e176fe5a665a28fd1c26a562cb1fa", "parents": [ "d210baf53b699fc61aa891c177b71d7082d3b957" ], "author": { "name": "Venkatesh Pallipadi", "email": "venkatesh.pallipadi@intel.com", "time": "Wed Sep 03 21:36:50 2008 +0000" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Sep 05 11:11:51 2008 +0200" }, "message": "clockevents: prevent clockevent event_handler ending up handler_noop\n\nThere is a ordering related problem with clockevents code, due to which\nclockevents_register_device() called after tickless/highres switch\nwill not work.
