buffers\n\nThese DMA drain buffer implementations in drivers are pretty horrible\nto do in terms of manipulating the scatterlist. Plus they\u0027re being\ndone at least in drivers/ide and drivers/ata, so we now have code\nduplication.\n\nThe one use case for this, as I understand it is AHCI controllers doing\nPIO mode to mmc devices but translating this to DMA at the controller\nlevel.\n\nSo, what about adding a callback to the block layer that permits the\nadding of the drain buffer for the problem devices. The idea is that\nyou\u0027d do this in slave_configure after you find one of these devices.\n\nThe beauty of doing it in the block layer is that it quietly adds the\ndrain buffer to the end of the sg list, so it automatically gets mapped\n(and unmapped) without anything unusual having to be done to the\nscatterlist in driver/scsi or drivers/ata and without any alteration to\nthe transfer length.\n\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "d38ecf935fcb10264a6bc190855d9595165e6eeb", "tree": "64e3146ef76678ad3ae8f75c32df9f25ea470953", "parents": [ "fd0928df98b9578be8a786ac0cb78a47a5e17a20" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu Jan 24 08:53:35 2008 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Mon Jan 28 10:50:31 2008 +0100" }, "message": "io context sharing: preliminary support\n\nDetach task state from ioc, instead keep track of how many processes\nare accessing the ioc.\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "fd0928df98b9578be8a786ac0cb78a47a5e17a20", "tree": "70a34cf207bea1bec28e59cf0dba7d20e7f8b0f1", "parents": [ "91525300baf162e83e923b09ca286f9205e21522" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu Jan 24 08:52:45 2008 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Mon Jan 28 10:50:29 2008 +0100" }, "message": "ioprio: move io priority from task_struct to io_context\n\nThis is where it belongs and then it doesn\u0027t take up space for a\nprocess that doesn\u0027t do IO.\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "5450d3e1d68f10be087f0855d8bad5458b50ecbe", "tree": "400126ac131621229c49c549f27838fcf3a263e7", "parents": [ "3bcddeac1c4c7e6fb90531b80f236b1a05dfe514" ], "author": { "name": "Kiyoshi Ueda", "email": "k-ueda@ct.jp.nec.com", "time": "Tue Dec 11 17:53:03 2007 -0500" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Mon Jan 28 10:37:13 2008 +0100" }, "message": "blk_end_request: cleanup \u0027uptodate\u0027 related code (take 4)\n\nThis patch converts \u0027uptodate\u0027 arguments of no longer exported\ninterfaces, end_that_request_first/last, to \u0027error\u0027, and removes\ninternal conversions for it in blk_end_request interfaces.\n\nAlso, this patch removes no longer needed end_io_error().\n\nCc: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nSigned-off-by: Kiyoshi Ueda \u003ck-ueda@ct.jp.nec.com\u003e\nSigned-off-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "3bcddeac1c4c7e6fb90531b80f236b1a05dfe514", "tree": "68e1f33b8176ff00552b1df92d16c23c28b0ecf2", "parents": [ "610d8b0c972e3b75493efef8e96175518fd736d3" ], "author": { "name": "Kiyoshi Ueda", "email": "k-ueda@ct.jp.nec.com", "time": "Tue Dec 11 17:52:28 2007 -0500" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Mon Jan 28 10:37:12 2008 +0100" }, "message": "blk_end_request: remove/unexport end_that_request_* (take 4)\n\nThis patch removes the following functions:\n o end_that_request_first()\n o end_that_request_chunk()\nand stops exporting the functions below:\n o end_that_request_last()\n\nCc: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nSigned-off-by: Kiyoshi Ueda \u003ck-ueda@ct.jp.nec.com\u003e\nSigned-off-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "e3a04fe34a3ec81ddeddb6c73fb7299716cffbb0", "tree": "080d1ec1cc3d78b3aef4e95f5334f5b4c3da3498", "parents": [ "aaa04c28cb9a1efd42541fdb7ab648231c2a2263" ], "author": { "name": "Kiyoshi Ueda", "email": "k-ueda@ct.jp.nec.com", "time": "Tue Dec 11 17:51:46 2007 -0500" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Mon Jan 28 10:37:08 2008 +0100" }, "message": "blk_end_request: add bidi completion interface (take 4)\n\nThis patch adds a variant of the interface, blk_end_bidi_request(),\nwhich completes a bidi request.\n\nBidi request must be completed as a whole, both rq and rq-\u003enext_rq\nat once.

Not all embedded devices require\nit, some can make do with just JFFS2, NFS, ramfs, etc - none of which require\nthe block layer to be present.\n\nThis patch does the following:\n\n (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev\n support.\n\n (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls\n an item that uses the block layer. This includes:\n\n (*) Block I/O tracing.\n\n (*) Disk partition code.\n\n (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.\n\n (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the\n \t block layer to do scheduling. Some drivers that use SCSI facilities -\n \t such as USB storage - end up disabled indirectly from this.\n\n (*) Various block-based device drivers, such as IDE and the old CDROM\n \t drivers.\n\n (*) MTD blockdev handling and FTL.\n\n (*) JFFS - which uses set_bdev_super(), something it could avoid doing by\n \t taking a leaf out of JFFS2\u0027s book.\n\n (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and\n linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,\n however, still used in places, and so is still available.\n\n (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and\n parts of linux/fs.h.\n\n (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.\n\n (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.\n\n (*) set_page_dirty() doesn\u0027t call __set_page_dirty_buffers() if CONFIG_BLOCK\n is not enabled.\n\n (*) fs/no-block.c is created to hold out-of-line stubs and things that are\n required when CONFIG_BLOCK is not set:\n\n (*) Default blockdev file operations (to give error ENODEV on opening).\n\n (*) Makes some /proc changes:\n\n (*) /proc/devices does not list any blockdevs.\n\n (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.\n\n (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.\n\n (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if\n given command other than Q_SYNC or if a special device is specified.\n\n (*) In init/do_mounts.c, no reference is made to the blockdev routines if\n CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.\n\n (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return\n error ENOSYS by way of cond_syscall if so).\n\n (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if\n CONFIG_BLOCK is not set, since they can\u0027t then happen.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "5404bc7a87b9949cf61e0174b21f80e73239ab25", "tree": "230c799aef2dcad8c64da55114508d28d2b30183", "parents": [ "da20a20f3b5c175648fa797c899dd577e4dacb51" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Thu Aug 10 09:01:02 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:29:42 2006 +0200" }, "message": "[PATCH] Allow file systems to differentiate between data and meta reads\n\nWe can use this information for making more intelligent priority\ndecisions, and it will also be useful for blktrace.\n\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "dc72ef4ae35c2016fb594bcc85ce871376682174", "tree": "c0c78879addf0d65adcc8f8cce01165fa2502dac", "parents": [ "981a79730d586335ef8f942c83bdf2b1de6d4e3d" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Thu Jul 20 14:54:05 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:29:40 2006 +0200" }, "message": "[PATCH] Add blk_start_queueing() helper\n\nCFQ implements this on its own now, but it\u0027s really block layer\nknowledge.

For io schedulers such as CFQ,\nthis will cause us lost merges and suboptimal behaviour in scheduling.\n\nRemove PF_SYNCWRITE completely from the fsync/msync paths, and let\nthe O_DIRECT path just directly indicate that the writes are sync\nby using WRITE_SYNC instead.\n\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "28e4b224955cbe30275b2a7842e729023a4f4b03", "tree": "ab4d28fecc06070fc2a2742f4b4550b29de44912", "parents": [ "22ae813b85df7c0b0fc7c8d6f336d6a9f566ff97", "67d59dfdeb21df2c16dcd478b66177e91178ecd0" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jun 21 11:18:25 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jun 21 11:18:25 2006 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6\n\n* master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (85 commits)\n [SCSI] 53c700: remove reliance on deprecated cmnd fields\n [SCSI] hptiop: don\u0027t use cmnd-\u003ebufflen\n [SCSI] hptiop: HighPoint RocketRAID 3xxx controller driver\n [SCSI] aacraid: small misc. cleanups\n [SCSI] aacraid: Update supported product information\n [SCSI] aacraid: Fix return code interpretation\n [SCSI] scsi_transport_sas: fix panic in sas_free_rphy\n [SCSI] remove RQ_SCSI_* flags\n [SCSI] remove scsi_request infrastructure\n [SCSI] mptfusion: change driver revision to 3.03.10\n [SCSI] mptfc: abort of board reset leaves port dead requiring reboot\n [SCSI] mptfc: fix fibre channel infinite request/response loop\n [SCSI] mptfc: set fibre channel fw target missing timers to one second\n [SCSI] mptfusion: move fc event/reset handling to mptfc\n [SCSI] spi transport: don\u0027t allow dt to be set on SE or HVD buses\n [SCSI] aic7xxx: expose the bus setting to sysfs\n [SCSI] scsi: remove Documentation/scsi/cpqfc.txt\n [SCSI] drivers/scsi: Use ARRAY_SIZE macro\n [SCSI] Remove last page_address from dc395x.c\n [SCSI] hptiop: HighPoint RocketRAID 3xxx controller driver\n ...\n\nFixed up conflicts in drivers/message/fusion/mptbase.c manually (due to\nthe sparc interrupt cleanups)\n" }, { "commit": "8d7feac3c7504425aaf61dc7d804685a6b89ee43", "tree": "0dd98c8cbfea10bdc748951cf9dc10b44f0042eb", "parents": [ "beb40487508290f5d6565598c60a3f44261beef2" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Sat Jun 10 18:37:19 2006 +0200" }, "committer": { "name": "James Bottomley", "email": "jejb@mulgrave.il.steeleye.com", "time": "Sat Jun 10 16:25:21 2006 -0500" }, "message": "[SCSI] remove RQ_SCSI_* flags\n\nThe RQ_SCSI_* flags are a vestiage of a long past history.
