Neither was acceptable.\n Moving to a registration solves this, and also limits the scope of\n the changes to something that could be backported to a distro without\n breaking an already-released-distro kabi. However, I admit it isn\u0027t\n as elegant, as the passing of the LLDD host template in the\n registration and the complexity around dynamic add/remove shows.\n\n- The receive path was augmented to require a unique identifier for\n the LLDD before the message was allowed to be handed off to the\n driver. Given how quickly very fatal errors occur if there\u0027s msg\n mismatches (which I saw in testing my own tools :), I believe this\n to be a very good thing. The id plays off the vendor id scheme already\n introduced for the vendor unique event messages used by FC.\n Additionally, the id use as the basis of the registration/deregistration.\n\n- Send assist functions, for both the transport and LLDDs are included.\n\n[fujita.tomonori@lab.ntt.co.jp: fix missing cast]\nSigned-off-by: James Smart \u003cjames.smart@emulex.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n" }, { "commit": "01b291bd66564b4bd826326af6bd0b6d17e99439", "tree": "89ba1f339a68827c1ea0e434629759a9252b0a69", "parents": [ "bb0003c1e189d5766b6b39299b08c690c985c4dc" ], "author": { "name": "James Bottomley", "email": "James.Bottomley@HansenPartnership.com", "time": "Thu Aug 21 15:14:14 2008 -0500" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@HansenPartnership.com", "time": "Fri Aug 29 09:19:11 2008 -0500" }, "message": "[SCSI] fix check of PQ and PDT bits for WLUNs\n\nFor IBM z series certain LUNs can no longer be accessed.\n\nThis is because kernel version 2.6.19 a check was introduced not to\ncreate a generic SCSI device for devices that return PQ\u003d1 and\nPDT\u003d0x1f.

The flag is enabled for all USB devices.\n\nThis revealed a second bug in other usb cardreaders, which crash when they\nget a multiple sector read which stops 1 sector short of the last sector.\nAffected hardware includes the Kingston \"MobileLite\" external USB cardreader\nand the internal USB cardreader on the Asus EeePC.\n\nExtend the last_sector_bug workaround to ensure that any access which touches\nthe last 8 hardware sectors of the device is a single sector long.

If the DVD contains data beyond the physical size of a CD, you\n get I/O errors in the terminal, and dmesg reports lots of\n \"attempt to access beyond end of device\" errors.\"\n\nwhich in turn is because the nested open after the media change won\u0027t\ncause the size to be set properly (because the original open still holds\nthe block device, and we only do the bd_set_size() when we don\u0027t have\nother people holding the device open).\n\nThe proper fix for that is probably to just do something like\n\n\tbdev-\u003ebd_inode-\u003ei_size \u003d (loff_t)get_capacity(disk)\u003c\u003c9;\n\nin fs/block_dev.c:do_open() even for the cases where we\u0027re not the\noriginal opener (but *not* call bd_set_size(), since that will also\nchange the block size of the device).\n\nCc: Peter Osterlund \u003cpetero2@telia.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ac40532ef0b8649e6f7f83859ea0de1c4ed08a19", "tree": "ca86d577fe7fe68ae28b7f7d020f86bc9fff5535", "parents": [ "158a962422e4a54dc256b6a9b9562f3d30d34d9c" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 02 17:25:34 2008 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Jan 02 13:11:06 2008 -0800" }, "message": "scsi: revert \"[SCSI] Get rid of scsi_cmnd-\u003edone\"\n\nThis reverts commit 6f5391c283d7fdcf24bf40786ea79061919d1e1d (\"[SCSI]\nGet rid of scsi_cmnd-\u003edone\") that was supposed to be a cleanup commit,\nbut apparently it causes regressions:\n\n Bug 9370 - v2.6.24-rc2-409-g9418d5d: attempt to access beyond end of device\n http://bugzilla.kernel.org/show_bug.cgi?id\u003d9370\n\nthis patch should be reintroduced in a more split-up form to make\ntesting of it easier.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "522939d45c293388e6a360210905f9230298df16", "tree": "38c37c6688a5095ab49c8fd42425e2bf3fb61ae9", "parents": [ "794e64d5e9c7f088378e093a48eb36a30091d82d" ], "author": { "name": "Maciej W.
