The conversion was done under the assumption that\nwhen a request fails residue count wasn\u0027t defined. However, Boaz and\nJames pointed out that this wasn\u0027t true and the residue count should\nbe preserved for failed requests too.\n\nThis patchset restores the original behavior by setting rq-\u003eresid_len\nto blk_rq_bytes(rq) on request start and restoring explicit clearing\nin affected drivers. While at it, take advantage of the fact that\nrq-\u003eresid_len is set to full count where applicable.\n\n* ide-cd: rq-\u003eresid_len cleared on pc success\n\n* mptsas: req-\u003eresid_len cleared on success\n\n* sas_expander: rsp/req-\u003eresid_len cleared on success\n\n* mpt2sas_transport: req-\u003eresid_len cleared on success\n\n* ide-cd, ide-tape, mptsas, sas_host_smp, mpt2sas_transport, ub: take\n advantage of initial full count to simplify code\n\nBoaz Harrosh spotted bug in resid_len initialization.

It could be\nthe total request length or it coulde be anything else one of the\nlower layers is using to keep track of residual count. This\ncomplicates things because blk_rq_bytes() and thus\n[__]blk_end_request_all() relies on rq-\u003edata_len for PC commands.\nDrivers which want to report residual count should first cache the\ntotal request length, update rq-\u003edata_len and then complete the\nrequest with the cached data length.\n\nSecondly, it makes requests default to reporting full residual count,\nie. reporting that no data transfer occurred. The residual count is\nan exception not the norm; however, the driver should clear\nrq-\u003edata_len to zero to signify the normal cases while leaving it\nalone means no data transfer occurred at all. This reverse default\nbehavior complicates code unnecessarily and renders block PC on some\ndrivers (ide-tape/floppy) unuseable.\n\nThis patch adds rq-\u003eresid_len which is used only for residual count.\n\nWhile at it, remove now unnecessasry blk_rq_bytes() caching in\nide_pc_intr() as rq-\u003edata_len is not changed anymore.\n\nBoaz\t: spotted missing conversion in osd\nSergei\t: spotted too early conversion to blk_rq_bytes() in ide-tape\n\n[ Impact: cleanup residual count handling, report 0 resid by default ]\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: Bartlomiej Zolnierkiewicz \u003cbzolnier@gmail.com\u003e\nCc: Borislav Petkov \u003cpetkovbb@googlemail.com\u003e\nCc: Sergei Shtylyov \u003csshtylyov@ru.mvista.com\u003e\nCc: Mike Miller \u003cmike.miller@hp.com\u003e\nCc: Eric Moore \u003cEric.Moore@lsi.com\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Doug Gilbert \u003cdgilbert@interlog.com\u003e\nCc: Mike Miller \u003cmike.miller@hp.com\u003e\nCc: Eric Moore \u003cEric.Moore@lsi.com\u003e\nCc: Darrick J.

ATA mode doesn\u0027t need any new driver\nand currently works well under standard IDE subsystem. Actually it\u0027s one\nchip SSD. IO mode is ATA-like custom mode for the host that doesn\u0027t have\nIDE interface.\n\nFollowings are brief descriptions about IO mode.\nA. IO mode based on ATA protocol and uses some custom command. (read confirm,\nwrite confirm)\nB. IO mode uses SRAM bus interface.\nC. IO mode supports 4kB boot area, so host can boot from mflash.\n\nThis driver is quitely similar to a standard ATA driver, but because of\nfollowing reasons it is currently seperated with ATA layer.\n\n1. ATA layer deals standard ATA protocol. ATA layer have many low-\n level device specific interface, but data transfer keeps ATA rule.\n But, mflash IO mode doesn\u0027t.\n\n2. Even though currently not used in mflash driver code, mflash has\n some custom command and modes. (nand fusing, firmware patch, etc) If\n this feature supported in linux kernel, ATA layer more altered.\n\n3. Currently PATA platform device driver doesn\u0027t support interrupt.\n (I\u0027m not sure) But, mflash uses interrupt (polling mode is just for\n debug).\n\n4. mflash is somewhat under-develop product. Even though some company\n already using mflash their own product, I think more time is needed for\n standardization of custom command and mode. That time (maybe October)\n I will talk to with ATA people.

This is a departure from any storage we have\nsupported in the past. We need some way to detect changes on the topology\nso we implement this kernel thread. In some instances there\u0027s nothing we\ncan do from the driver (like LUN failure) so just print out a message. In\nthe case where logical volumes are added or deleted we call\nrebuild_lun_table to refresh the driver\u0027s view of the world.\n\nSigned-off-by: Mike Miller \u003cmike.miller@hp.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "ac44e5b2ed62bf4acf9df84575d3f18c7a6fdf22", "tree": "55e44b1d54299f85332e6e1087cad28e9a439c33", "parents": [ "26308eab69aa193f7b3fb50764a64ae14544a39b" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Fri Mar 27 10:43:52 2009 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Apr 07 08:12:38 2009 +0200" }, "message": "cciss: fix residual count for block pc requests\n\nWe must complete the full request, so store the request count and then set\nthe -\u003edata_len to the residual count from the hardware.\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "ea02259fdf47ca81ff3ca0c22906d989094fb8ff", "tree": "5d3672aa246e016f695bc62a861902a50de7b461", "parents": [ "8fe74cf053de7ad2124a894996f84fa890a81093", "eae6c2b6414fc6673ac5415442fe463c01005366" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 03 09:02:32 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 03 09:02:32 2009 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/bart/linux-hdreg-h-cleanup\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/bart/linux-hdreg-h-cleanup:\n remove \u003clinux/ata.h\u003e include from \u003clinux/hdreg.h\u003e\n include/linux/hdreg.h: remove unused defines\n isd200: use ATA_* defines instead of *_STAT and *_ERR ones\n include/linux/hdreg.h: cover WIN_* and friends with #ifndef/#endif __KERNEL__\n aoe: WIN_* -\u003e ATA_CMD_*\n isd200: WIN_* -\u003e ATA_CMD_*\n include/linux/hdreg.h: cover struct hd_driveid with #ifndef/#endif __KERNEL__\n xsysace: make it \u0027struct hd_driveid\u0027-free\n ubd_kern: make it \u0027struct hd_driveid\u0027-free\n isd200: make it \u0027struct hd_driveid\u0027-free\n" }, { "commit": "15746fcaa3a00753bbab2326088b85b10c1ba36a", "tree": "a61e2e83fc3eaefc62f2e45d1b95125a8180c7ab", "parents": [ "1a2ad21128bb4eb79f3c05e5801edcc5ed3ef1d3" ], "author": { "name": "Pavel Machek", "email": "pavel@suse.cz", "time": "Thu Apr 02 16:58:42 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 02 19:05:02 2009 -0700" }, "message": "nbd: trivial cleanups\n\nTrivial cleanups for nbd: only the return -EIO one really changes code,\nand I\u0027ve verified all the callers (plus 0 \u003d\u003d success, 1 \u003d\u003d error\nconvention is really ugly).\n\nSigned-off-by: Pavel Machek \u003cpavel@suse.cz\u003e\nAcked-by: Paul Clements \u003cpaul.clements@steeleye.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1a2ad21128bb4eb79f3c05e5801edcc5ed3ef1d3", "tree": "ba5845f5e7f225b427d4ce250b911b9303aa9511", "parents": [ "1b0f7ffd0ea27cd3a0b9ca04e3df9522048c32a3" ], "author": { "name": "Pavel Machek", "email": "pavel@suse.cz", "time": "Thu Apr 02 16:58:41 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 02 19:05:02 2009 -0700" }, "message": "nbd: add locking to nbd_ioctl\n\nThe code was written to rely on big kernel lock to protect it from races.\nIt mostly works when interface is not abused.\n\nSo this uses tx_lock to protect data structures from concurrent use\nbetween ioctl and worker threads.\n\nNext step will be moving from ioctl to unlocked_ioctl.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: add missing return]\nSigned-off-by: Pavel Machek \u003cpavel@suse.cz\u003e\nAcked-by: Paul Clements \u003cpaul.clements@steeleye.com\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "83f9ef463bcb4ba7b4fee1d6212fac7d277010d3" }
