      "message": "[SCSI] sd,sr: kill compat SDEV_MEDIA_CHANGE event\n\nSDEV_MEDIA_CHANGE event was first added by commit a341cd0f (SCSI: add\nasynchronous event notification API) for SATA AN support and then\nextended to cover generic media change events by commit 285e9670\n([SCSI] sr,sd: send media state change modification events).\n\nThis event was mapped to block device in userland with all properties\nstripped to simulate CHANGE event on the block device, which, in turn,\nwas used to trigger further userspace action on media change.\n\nThe recent addition of disk event framework kept this event for\nbackward compatibility but it turns out to be unnecessary and causes\nerratic and inefficient behavior.  The new disk event generates proper\nevents on the block devices and the compat events are mapped to block\ndevice with all properties stripped, so the block device ends up\ngenerating multiple duplicate events for single actual event.\n\nThis patch removes the compat event generation from both sr and sd as\nsuggested by Kay Sievers.  Both existing and newer versions of udev\nand the associated tools will behave better with the removal of these\nevents as they from the beginning were expecting events on the block\ndevices.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n"

      "message": "[SCSI] fix medium error problems with some arrays which can cause data corruption\n\nOur current handling of medium error assumes that data is returned up\nto the bad sector.  This assumption holds good for all disk devices,\nall DIF arrays and most ordinary arrays.  However, an LSI array engine\nwas recently discovered which reports a medium error without returning\nany data.  This means that when we report good data up to the medium\nerror, we\u0027ve reported junk originally in the buffer as good.  Worse,\nif the read consists of requested data plus a readahead, and the error\noccurs in readahead, we\u0027ll just strip off the readahead and report\njunk up to userspace as good data with no error.\n\nThe fix for this is to have the error position computation take into\naccount the amount of data returned by the driver using the scsi\nresidual data.  Unfortunately, not every driver fills in this data,\nbut for those who don\u0027t, it\u0027s set to zero, which means we\u0027ll think a\nfull set of data was transferred and the behaviour will be identical\nto the prior behaviour of the code (believe the buffer up to the error\nsector).  All modern drivers seem to set the residual, so that should\nfix up the LSI failure/corruption case.\n\nReported-by: Douglas Gilbert \u003cdgilbert@interlog.com\u003e\nCc: Stable Tree \u003cstable@kernel.org\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n"

      "message": "[SCSI] Retrieve the Caching mode page\n\nSome kernel transport drivers unconditionally disable\nretrieval of the Caching mode page. One such for example is\nthe BBB/CBI transport over USB.  Such a restraint is too\nharsh as some devices do support the Caching mode\npage. Unconditionally enabling the retrieval of this mode\npage over those transports at their transport code level may\nresult in some devices failing and becoming unusable.\n\nThis patch implements a method of retrieving the Caching\nmode page without unconditionally enabling it in the\ntransports which unconditionally disable it. The idea is to\nask for all supported pages, page code 0x3F, and then search\nfor the Caching mode page in the mode parameter data\nreturned. The sd driver already asks for all the mode pages\nsupported by the attached device by setting the page code to\n0x3F in order to find out if the media is write protected by\nreading the WP bit in the Device Specific Parameter\nfield. It then attempts to retrieve only the Caching mode\npage by setting the page code to 8 and actually attempting\nto retrieve it if and only if the transport allows it.\n\nThe method implemented here is that if the transport doesn\u0027t\nallow retrieval of the Caching mode page and the device is\nnot RBC, then we ask for all pages supported by setting the\npage code to 0x3F (similarly to how the WP bit is retrieved\nabove), and then we search for the Caching mode page in the\nmode parameter data returned.\n\nWith this patch, devices over SATA, report this (no change):\n\nOct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] 976773168 512-byte logical blocks: (500 GB/465 GiB)\nOct 22 18:45:58 localhost kernel: sd 0:0:0:0: Attached scsi generic sg0 type 0\nOct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Write Protect is off\nOct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00\nOct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn\u0027t support DPO or FUA\n\nSmart devices report their Caching mode page.

So this time a\nfriend of mine asked me to get an mp4 player (an mp3 player which can play\nvideos on a small screen) to work with Linux.\n\nIt is based on the well known rockbox chipset for which we already have an\nunusual devs entries to work around some of its bugs.  But this model\ncomes with an additional twist.\n\nThis model chokes on read_capacity_16 calls.  Now normally we don\u0027t make\nthose calls, but this model comes with an sdcard slot and when there is no\ncard in there (and shipped from the factory there is none), it reports a\nsize of 0.  However this time the programmers actually got the\nread_capacity_10 response right!  So they substract one from the size as\nstored internally in the mp3 player before reporting it back, resulting in\nan answer of ...  0xffffffff sectors, causing sd.c to try a\nread_capacity_16, on which the device crashes.\n\nThis patch adds a flag to scsi_device to indicate that a a device cannot\nhandle read_capacity_16, and when this flag is set if a device reports an\nlba of 0xffffffff as answer to a read_capacity_10, assumes it tries to\nreport a size of 0.\n\nSigned-off-by: Hans de Goede \u003chdegoede@redhat.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: Matthew Dharm \u003cmdharm-usb@one-eyed-alien.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability.  As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n  http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n  only the necessary includes are there.  ie. if only gfp is used,\n  gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n  blocks and try to put the new include such that its order conforms\n  to its surrounding.  It\u0027s put in the include block which contains\n  core kernel includes, in the same order that the rest are ordered -\n  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n  doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n  because the file doesn\u0027t have fitting include block), it prints out\n  an error message indicating which .h file needs to be added to the\n  file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n   over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n   and ~3000 slab.h inclusions.  The script emitted errors for ~400\n   files.\n\n2. Each error was manually checked.  Some didn\u0027t need the inclusion,\n   some needed manual addition while adding it to implementation .h or\n   embedding .c file was more appropriate for others.  This step added\n   inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n   from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n   e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n   APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n   editing them as sprinkling gfp.h and slab.h inclusions around .h\n   files could easily lead to inclusion dependency hell.  Most gfp.h\n   inclusion directives were ignored as stuff from gfp.h was usually\n   wildly available and often used in preprocessor macros.  Each\n   slab.h inclusion directive was examined and added manually as\n   necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my\n   distributed build env didn\u0027t work with gcov compiles) and a few\n   more options had to be turned off depending on archs to make things\n   build (like ipr on powerpc/64 which failed due to missing writeq).\n\n   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n   * powerpc and powerpc64 SMP allmodconfig\n   * sparc and sparc64 SMP allmodconfig\n   * ia64 SMP allmodconfig\n   * s390 SMP allmodconfig\n   * alpha SMP allmodconfig\n   * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n   a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n"

      "message": "block: unify request timeout handling\n\nRight now SCSI and others do their own command timeout handling.\nMove those bits to the block layer.\n\nInstead of having a timer per command, we try to be a bit more clever\nand simply have one per-queue.

      "message": "block: allow disk to have extended device number\n\nNow that disk and partition handlings are mostly unified, it\u0027s easy to\nallow disk to have extended device number.  This patch makes\nadd_disk() use extended device number if disk-\u003eminors is zero.  Both\nsd and ide-disk are updated to use this.\n\n* sd_format_disk_name() is implemented which can generically determine\n  the drive name.  This removes disk number restriction stemming from\n  limited device names.\n\n* If sd index goes over SD_MAX_DISKS (which can be increased now BTW),\n  sd simply doesn\u0027t initialize minors letting block layer choose\n  extended device number.\n\n* If CONFIG_DEBUG_EXT_DEVT is set, both sd and ide-disk always set\n  minors to 0 and use extended device numbers.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"
