For\nexample for the 32bit x86 node with 4Gb RAM, max_pfn \u003d 0x100000, but not\n0xFFFF.\n\nrequest_queue structure has a member q-\u003ebounce_pfn and queue needs bounce\npages for the pages _above_ this limit. This routine is handled by\nblk_queue_bounce(), where the following check is produced:\n\n\tif (q-\u003ebounce_pfn \u003e\u003d blk_max_pfn)\n\t\treturn;\n\nAssume, that a driver has set q-\u003ebounce_pfn to 0xFFFF, but blk_max_pfn\nequals 0x10000. In such situation the check above fails and for each bio\nwe always fall down for iterating over pages tied to the bio.\n\nI want to notice, that for quite a big range of device drivers (ide, md,\n...) such problem doesn\u0027t happen because they use BLK_BOUNCE_ANY for\nbounce_pfn. BLK_BOUNCE_ANY is defined as blk_max_pfn \u003c\u003c PAGE_SHIFT, and\nthen the check above doesn\u0027t fail. But for other drivers, which obtain\nreuired value from drivers, it fails. For example sata_nv uses\nATA_DMA_MASK or dev-\u003edma_mask.\n\nI propose to use (max_pfn - 1) for blk_max_pfn. And the same for\nblk_max_low_pfn. The patch also cleanses some checks related with\nbounce_pfn.\n\nSigned-off-by: Vasily Tarasov \u003cvtaras@openvz.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "387bb17374c5fa057462d00d4ba941d49f45de4d", "tree": "85c68bbd2f077724563cfb26a3357d6679f12104", "parents": [ "6649a3863232eb2e2f15ea6c622bd8ceacf96d76" ], "author": { "name": "Neil Brown", "email": "neilb@suse.de", "time": "Thu Feb 08 14:20:29 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 09 09:25:46 2007 -0800" }, "message": "[PATCH] md: fix various bugs with aligned reads in RAID5\n\nIt is possible for raid5 to be sent a bio that is too big for an underlying\ndevice.

context data\n\nPass the work_struct pointer to the work function rather than context data.\nThe work function can use container_of() to work out the data.\n\nFor the cases where the container of the work_struct may go away the moment the\npending bit is cleared, it is made possible to defer the release of the\nstructure by deferring the clearing of the pending bit.\n\nTo make this work, an extra flag is introduced into the management side of the\nwork_struct. This governs auto-release of the structure upon execution.\n\nOrdinarily, the work queue executor would release the work_struct for further\nscheduling or deallocation by clearing the pending bit prior to jumping to the\nwork function. This means that, unless the driver makes some guarantee itself\nthat the work_struct won\u0027t go away, the work function may not access anything\nelse in the work_struct or its container lest they be deallocated.. This is a\nproblem if the auxiliary data is taken away (as done by the last patch).\n\nHowever, if the pending bit is *not* cleared before jumping to the work\nfunction, then the work function *may* access the work_struct and its container\nwith no problems. But then the work function must itself release the\nwork_struct by calling work_release().\n\nIn most cases, automatic release is fine, so this is the default. Special\ninitiators exist for the non-auto-release case (ending in _NAR).\n\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "df66b8552be5fdab5c4b4d53ee08b99388b9bd02", "tree": "e206c3b5f1d5b95f0467196aece471569eee062f", "parents": [ "7bd473fcc217adec000f213e8864bf9a161d57e1" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Thu Nov 02 22:06:56 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Nov 03 12:27:55 2006 -0800" }, "message": "[PATCH] tidy \"md: check bio address after mapping through partitions\"\n\nNeil\u0027s xterms are too wide.\n\nCc: Neil Brown \u003cneilb@cse.unsw.edu.au\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5ddfe9691c91a244e8d1be597b6428fcefd58103", "tree": "d051fd7c370a7b8ad91f24c6f99f985b8b1252b2", "parents": [ "45ec4ababe999cb95f9c0cad03b2689cb0b77a2b" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Mon Oct 30 22:07:21 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Oct 31 08:07:01 2006 -0800" }, "message": "[PATCH] md: check bio address after mapping through partitions.\n\nPartitions are not limited to live within a device.

They have no\nessential function for the VM.\n\nWe use a simple increment of per cpu variables. In order to avoid the most\nsevere races we disable preempt. Preempt does not prevent the race between\nan increment and an interrupt handler incrementing the same statistics\ncounter. However, that race is exceedingly rare, we may only loose one\nincrement or so and there is no requirement (at least not in kernel) that\nthe vm event counters have to be accurate.\n\nIn the non preempt case this results in a simple increment for each\ncounter. For many architectures this will be reduced by the compiler to a\nsingle instruction. This single instruction is atomic for i386 and x86_64.\n And therefore even the rare race condition in an interrupt is avoided for\nboth architectures in most cases.\n\nThe patchset also adds an off switch for embedded systems that allows a\nbuilding of linux kernels without these counters.\n\nThe implementation of these counters is through inline code that hopefully\nresults in only a single instruction increment instruction being emitted\n(i386, x86_64) or in the increment being hidden though instruction\nconcurrency (EPIC architectures such as ia64 can get that done).\n\nBenefits:\n- VM event counter operations usually reduce to a single inline instruction\n on i386 and x86_64.\n- No interrupt disable, only preempt disable for the preempt case.\n Preempt disable can also be avoided by moving the counter into a spinlock.\n- Handling is similar to zoned VM counters.\n- Simple and easily extendable.\n- Can be omitted to reduce memory use for embedded use.\n\nReferences:\n\nRFC

Today if a LLD does not set it\nSCSI-ml sets it to a safe default and some LLDs set it to a artificial low\nvalue to overcome memory and feedback issues.\n\nNote: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024,\ndrivers that used to call blk_queue_max_sectors with a large value of\nmax_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.\n\nSigned-off-by: Mike Christie \u003cmichaelc@cs.wisc.edu\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@SteelEye.com\u003e\n" }, { "commit": "6e39b69e7ea9205c5f80aeac3ef999ab8fb1a4cc", "tree": "abf6bf248970a249cc15e0c3df75ae42833be084", "parents": [ "9e1fe9314cb5649b2dc73690f2cd8d0068e633d9" ], "author": { "name": "Mike Christie", "email": "michaelc@cs.wisc.edu", "time": "Fri Nov 11 05:30:24 2005 -0600" }, "committer": { "name": "James Bottomley", "email": "jejb@mulgrave.(none)", "time": "Wed Dec 14 19:00:50 2005 -0800" }, "message": "[SCSI] export blk layer functions needed for blk_execute_rq_nowait\n\nTo send async requests we need these two functions exported.\n\nSigned-off-by: Mike Christie \u003cmichaelc@cs.wisc.edu\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@SteelEye.com\u003e\n" }, { "commit": "eb97b73d75d5c9af7c78c05106de9e3fdc4455ab", "tree": "b5e87f732a72cb3cdff96f7116906ed6a2f9643e", "parents": [ "811803c5572b296e0031e0099203de90d77c7bcf" ], "author": { "name": "Coywolf Qi Hunt", "email": "qiyong@fc-cn.com", "time": "Wed Nov 16 15:27:24 2005 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Fri Nov 18 21:59:31 2005 +0100" }, "message": "[BLOCK] new block/ directory comment tidy\n\nSome leftover comments referring to drivers/block that are now block/.\nThey don\u0027t add any information we don\u0027t already have, so kill them.\n\nSigned-off-by: Coywolf Qi Hunt \u003cqiyong@fc-cn.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "333c47c847c90aaefde8b593054d9344106333b5", "tree": "a4aec7b18ffe8d8dd88e027e5e4d84b2d838fe8a", "parents": [ "8f0cb147b2fb12427bf6abef7fed2b604557a41e", "c6ea2ba7b8acdb6c4a883b2d38607c8078dff4ee" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Nov 07 08:32:39 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Nov 07 08:32:39 2005 -0800" }, "message": "Merge branch \u0027block-dir\u0027 of git://brick.kernel.dk/data/git/linux-2.6-block\n" }, { "commit": "3a65dfe8c088143c7155cfd36a72f4b0ad2fc4b2", "tree": "db930c9f71f94d3ee674f65e38c38e95ca97227e", "parents": [ "0f3278d14f0255e4cd9e07ccefc33ff12d8bb59c" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Fri Nov 04 08:43:35 2005 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Fri Nov 04 08:43:35 2005 +0100" }, "message": "[BLOCK] Move all core block layer code to new block/ directory\n\ndrivers/block/ is right now a mix of core and driver parts.
