The result is very confusing\nstandby behaviour (using hdparm -y). If you suspend a drive and then send\nanother command, usually it wakes up. However, if the next command is a TEST\nUNIT READY, the SATL sees that the drive is suspended and proceeds to follow\nthe SATL rules for this, returning NOT READY to all subsequent commands. This\nmeans that the ordering of TEST UNIT READY is crucial: if you send TUR and\nthen a command, you get a NOT READY to both back. If you send a command and\nthen a TUR, you get GOOD status because the preceeding command woke the drive.\n\nThis bit us badly because\n\ncommit 85ef06d1d252f6a2e73b678591ab71caad4667bb\nAuthor: Tejun Heo \u003ctj@kernel.org\u003e\nDate: Fri Jul 1 16:17:47 2011 +0200\n\n block: flush MEDIA_CHANGE from drivers on close(2)\n\nChanged our ordering on TEST UNIT READY commands meaning that SATA drives\nconnected to an mpt2sas now suspend and refuse to wake (because the mpt2sas\nSATL sees the suspend *before* the drives get awoken by the next ATA command)\nresulting in lots of failed commands.\n\nThe standard is completely nuts forcing this inconsistent behaviour, but we\nhave to work around it.\n\nThe fix for this is twofold:\n\n 1. Set the allow_restart flag so we wake the drive when we see it has been\n suspended\n\n 2. Return all TEST UNIT READY status directly to the mid layer without any\n further error handling which prevents us causing error handling which\n may offline the device just because of a media check TUR.\n\nReported-by: Matthias Prager \u003clinux@matthiasprager.de\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "7a4601c0bfde4ed50c54f30c32c5677e3daec4f9", "tree": "54dcd326a9b53c50fc085940ee0837c8ae36046e", "parents": [ "797efad403c63c9a94a8f78e06ccb3aa5b4980a9" ], "author": { "name": "sreekanth.reddy@lsi.com", "email": "sreekanth.reddy@lsi.com", "time": "Tue Jul 17 15:57:05 2012 +0530" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Sep 14 10:00:25 2012 -0700" }, "message": "SCSI: mpt2sas: Fix for Driver oops, when loading driver with max_queue_depth command line option to a very small value\n\ncommit 338b131a3269881c7431234855c93c219b0979b6 upstream.\n\nIf the specified max_queue_depth setting is less than the\nexpected number of internal commands, then driver will calculate\nthe queue depth size to a negitive number.

See also\nhttp://www.spinics.net/lists/linux-scsi/msg56254.html.\n\nOther changes included in this patch:\n- Swap the blk_cleanup_queue() and kfree() calls in\n scsi_host_dev_release() to make that code easier to grasp.\n- Remove the queue dead check from scsi_run_queue() since the\n queue state can change anyway at any point in that function\n where the queue lock is not held.\n- Remove the queue dead check from the start of scsi_request_fn()\n since it is redundant with the scsi_device_online() check.\n\nReported-by: Jun\u0027ichi Nomura \u003cj-nomura@ce.jp.nec.com\u003e\nSigned-off-by: Bart Van Assche \u003cbvanassche@acm.org\u003e\nReviewed-by: Mike Christie \u003cmichaelc@cs.wisc.edu\u003e\nReviewed-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "f07d3f59e35eb0fc8847587f601f84b8cfa8dd38", "tree": "595db5361b5b316648b0d3b9bea7a4daf4ccd0a0", "parents": [ "bb12049078a3a69f750779a19287cd4ac5f2bc3e" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Thu Jun 21 23:47:28 2012 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Aug 09 08:31:28 2012 -0700" }, "message": "SCSI: fix hot unplug vs async scan race\n\ncommit 3b661a92e869ebe2358de8f4b3230ad84f7fce51 upstream.\n\nThe following crash results from cases where the end_device has been\nremoved before scsi_sysfs_add_sdev has had a chance to run.\n\n BUG: unable to handle kernel NULL pointer dereference at 0000000000000098\n IP: [\u003cffffffff8115e100\u003e] sysfs_create_dir+0x32/0xb6\n ...\n Call Trace:\n [\u003cffffffff8125e4a8\u003e] kobject_add_internal+0x120/0x1e3\n [\u003cffffffff81075149\u003e] ? trace_hardirqs_on+0xd/0xf\n [\u003cffffffff8125e641\u003e] kobject_add_varg+0x41/0x50\n [\u003cffffffff8125e70b\u003e] kobject_add+0x64/0x66\n [\u003cffffffff8131122b\u003e] device_add+0x12d/0x63a\n [\u003cffffffff814b65ea\u003e] ? _raw_spin_unlock_irqrestore+0x47/0x56\n [\u003cffffffff8107de15\u003e] ? module_refcount+0x89/0xa0\n [\u003cffffffff8132f348\u003e] scsi_sysfs_add_sdev+0x4e/0x28a\n [\u003cffffffff8132dcbb\u003e] do_scan_async+0x9c/0x145\n\n...teach scsi_sysfs_add_devices() to check for deleted devices() before\ntrying to add them, and teach scsi_remove_target() how to remove targets\nthat have not been added via device_add().\n\nReported-by: Dariusz Majchrzak \u003cdariusz.majchrzak@intel.com\u003e\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "bb12049078a3a69f750779a19287cd4ac5f2bc3e", "tree": "f2e36507a9d980ebccc006db141ff6e65cb40c9d", "parents": [ "1c06102701a00d42f2c690d97cc2203d561ea6a4" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Thu Jun 21 23:25:32 2012 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Aug 09 08:31:27 2012 -0700" }, "message": "SCSI: fix eh wakeup (scsi_schedule_eh vs scsi_restart_operations)\n\ncommit 57fc2e335fd3c2f898ee73570dc81426c28dc7b4 upstream.\n\nRapid ata hotplug on a libsas controller results in cases where libsas\nis waiting indefinitely on eh to perform an ata probe.\n\nA race exists between scsi_schedule_eh() and scsi_restart_operations()\nin the case when scsi_restart_operations() issues i/o to other devices\nin the sas domain.

They\nreport bogus sizes, in some cases becoming unusable as a result.\n\nThe bugs were triggered by commit\n09b6b51b0b6c1b9bb61815baf205e4d74c89ff04 (SCSI \u0026 usb-storage: add\nflags for VPD pages and REPORT LUNS), which caused usb-storage to stop\noverriding the SCSI level reported by devices. By default, the sd\ndriver will try READ CAPACITY(16) first for any device whose level is\nabove SCSI_SPC_2.\n\nIt seems likely that any device large enough to require the use of\nREAD CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ\nCAPACITY(10) commands properly. Indeed, I don\u0027t know of any devices\nthat don\u0027t handle READ CAPACITY(10) properly.\n\nTherefore this patch (as1559) adds a new flag telling the sd driver\nto try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag\nfor every USB mass-storage device.

This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that. We\u0027ll find out anything that got broken and fix it..\n\n* tag \u0027split-asm_system_h-for-linus-20120328\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits)\n Delete all instances of asm/system.h\n Remove all #inclusions of asm/system.h\n Add #includes needed to permit the removal of asm/system.h\n Move all declarations of free_initmem() to linux/mm.h\n Disintegrate asm/system.h for OpenRISC\n Split arch_align_stack() out from asm-generic/system.h\n Split the switch_to() wrapper out of asm-generic/system.h\n Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h\n Create asm-generic/barrier.h\n Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h\n Disintegrate asm/system.h for Xtensa\n Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt]\n Disintegrate asm/system.h for Tile\n Disintegrate asm/system.h for Sparc\n Disintegrate asm/system.h for SH\n Disintegrate asm/system.h for Score\n Disintegrate asm/system.h for S390\n Disintegrate asm/system.h for PowerPC\n Disintegrate asm/system.h for PA-RISC\n Disintegrate asm/system.h for MN10300\n ...\n" }, { "commit": "47b816ff7d520509176154748713e7d66b3ad6ac", "tree": "6d14e8bf3a8d41f9d4cdd6ccdec91d3d6b046b05", "parents": [ "2e7580b0e75d771d93e24e681031a165b1d31071", "1ce447b90f3e71c81ae59e0062bc305ef267668b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 28 14:41:36 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 28 14:41:36 2012 -0700" }, "message": "Merge branch \u0027next\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc\n\nPull a few more things for powerpc by Benjamin Herrenschmidt:\n - Anton\u0027s did some recent improvements to EPOW event reporting on\n pSeries (power supply failures and such).

While this is beneficial to performance,\nits not safe to do, as it breaks the serialization of access to the lport\nstructure (i.e. when an fcoe interface is being torn down, theres no way to\nserialize the teardown effort with the completion of receieve operations\noccuring in softirq context. As a result, lport (and other) data structures can\nbe read and modified in parallel leading to corruption. Most notable is the\nvport list, which is protected by a mutex, that will cause a panic if a softirq\nreceive while said mutex is locked. Additionaly, the ema_list, discussed here:\n\nhttp://lists.open-fcoe.org/pipermail/devel/2012-February/011947.html\n\nCan be corrupted if a list traversal occurs in softirq context at the same time\nas a list delete in process context. And generally the lport state variables\nwill not be stable, and may lead to unpredictable results.\n\nThe most direct fix is to remove the bits from the above commit that allowed\nfcoe_recv_frame to be called in softirq context. We just force all frames to be\nhandled by the per-cpu rx threads. This will allow the fcoe_if_destroy\u0027s use of\nfcoe_percpu_clean to function properly, ensuring that no frames are being\nreceived while the lport is being torn down.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nReviewed-by: Vasu Dev \u003cvasu.dev@intel.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "b08c1856b4d4295040ec72f15427588087369220", "tree": "54e826e81447826233cd73c0bffddb5d2dc2094f", "parents": [ "a93107355d2d4557e7e19ea1724bdb710268cd34" ], "author": { "name": "Santosh Nayak", "email": "santoshprasadnayak@gmail.com", "time": "Fri Mar 09 13:43:38 2012 +0530" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Wed Mar 28 08:58:09 2012 +0100" }, "message": "[SCSI] pm8001: Use spin_lock_irqsave() for task_state.\n\nSigned-off-by: Santosh Nayak \u003csantoshprasadnayak@gmail.com\u003e\nAcked-by: Jack Wang \u003cjack_wang@usish.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "9e4db1c3eed55c22328d8022c2c80adb3093833f", "tree": "9643545e6bd182f1d3e19942f590a6a1e3198320", "parents": [ "de8856d2c11f562c60ed9340a83db4a4f829a6e6", "aae528d9a8ad79d4b21b1b723abc9447fdb0d200" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Mar 27 18:17:02 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Mar 27 18:17:02 2012 -0700" }, "message": "Merge branch \u0027platforms\u0027 of git://git.linaro.org/people/rmk/linux-arm\n\nPull ARM platform updates from Russell King:\n \"This covers platform stuff for platforms I have a direct interest in\n (iow, I have the hardware).
