A Google search reveals many people with the same issue\nbut no solution (cdrwtool fails to format the disk). After spending some\ntime tracking down the issue, it comes down to the following:\n\nThe udftools still use the older CDROM_SEND_PACKET interface to send\nthings like FORMAT_UNIT through to the drive. They should really be\nupdated, but that\u0027s another story. Since most distros are using libata\nnow, the cd or dvd burner appears as a SCSI device, and we wind up in\nblock/scsi_ioctl.c. Here, the code tries to take the \"struct\ncdrom_generic_command\" and translate it and stuff it into a \"struct\nsg_io_hdr\" structure so it can pass it to the modern sg_io() routine\ninstead. Unfortunately, there is one error, or rather an omission in the\ntranslation. The timeout that is passed in in the \"struct\ncdrom_generic_command\" is in HZ\u003d100 units, and this is modified and\ncorrectly converted to jiffies by use of clock_t_to_jiffies(). However,\na little further down, this cgc.timeout value in jiffies is simply\ncopied into the sg_io_hdr timeout, which should be in milliseconds.\nSince most modern x86 kernels seems to be getting build with HZ\u003d250, the\ntimeout that is passed to sg_io and eventually converted to the\ntimeout_per_command member of the scsi_cmnd structure is now four times\ntoo small. Since cdrwtool tries to set the timeout to one hour for the\nFORMAT_UNIT command, and it takes about 20 minutes to format a 4x CDRW,\nthe SCSI error-handler kicks in after the FORMAT_UNIT completes because\nit took longer than the incorrectly-calculated timeout.\n\n[jejb: fix up whitespace]\nSigned-off-by: Tim Wright \u003ctimw@splhi.com\u003e\nCc: Stable Tree

"sysfs: add /sys/dev/{char,block} to lookup sysfs path by major:minor\n\nWhy?:\nThere are occasions where userspace would like to access sysfs\nattributes for a device but it may not know how sysfs has named the\ndevice or the path. For example what is the sysfs path for\n/dev/disk/by-id/ata-ST3160827AS_5MT004CK? With this change a call to\nstat(2) returns the major:minor then userspace can see that\n/sys/dev/block/8:32 links to /sys/block/sdc.\n\nWhat are the alternatives?:\n1/ Add an ioctl to return the path: Doable, but sysfs is meant to reduce\n the need to proliferate ioctl interfaces into the kernel, so this\n seems counter productive.\n\n2/ Use udev to create these symlinks: Also doable, but it adds a\n udev dependency to utilities that might be running in a limited\n environment like an initramfs.\n\n3/ Do a full-tree search of sysfs.\n\n[kay.sievers@vrfy.org: fix duplicate registrations]\n[kay.sievers@vrfy.org: cleanup suggestions]\n\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Tejun Heo \u003chtejun@gmail.com\u003e\nAcked-by: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nReviewed-by: SL Baur \u003csteve@xemacs.org\u003e\nAcked-by: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nAcked-by: Mark Lord \u003clkml@rtr.ca\u003e\nAcked-by: H.

The slowdown is caused by the fact that when some\ncode calls unplug on the device mapper, device mapper calls unplug on all\nphysical disks. These unplug calls take the lock, find that the queue is\nalready unplugged, release the lock and exit.\n\nWith the below patch, performance of the benchmark was increased by 18%\n(the whole OLTP application, not just block layer microbenchmarks).\n\nSo I\u0027m submitting this patch for upstream. I think the patch is correct,\nbecause when more threads call simultaneously plug and unplug, it is\nunspecified, if the queue is or isn\u0027t plugged (so the patch can\u0027t make\nthis worse). And the caller that plugged the queue should unplug it\nanyway.
