"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.

It does\nthe batch switch only after all requests from the previous batch are\ncompleted.\n\nWhen switching to a write batch, if there is an on-going read request,\nit waits for its completion and indicates its intention of switching by\nsetting ad-\u003echanged_batch and the new direction but does not update the\nbatch_expire_time for the new write batch which it does in the case of\nno previous pending requests.\nOn completion of the read request, it sees that we were waiting for the\nswitch and schedules work for kblockd right away and resets the\nad-\u003echanged_data flag.\nNow when kblockd enters dispatch_request where it is expected to pick\nup a write request, it in turn ends the write batch because the\nbatch_expire_timer was not updated and shows the expire timestamp for\nthe previous batch.\n\nThis results in the write starvation for all the cases where there is\nthe intention for switching to a write batch, but there is a previous\nin-flight read request and the batch gets reverted to a read_batch\nright away.\n\nThis also holds true in the reverse case (switching from a write batch\nto a read batch with an in-flight write request).\n\nI\u0027ve checked that this bug exists on 2.6.11, 2.6.18, 2.6.24 and\nlinux-2.6-block git HEAD.

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.

For example, bsg takes a ref to the sdev_gendev for scsi\ndevices. However, bsg doesn\u0027t inrease the refcount in fops-\u003eopen. So\nwhile an application opens a bsg device, the scsi device that the bsg\ndevice holds can go away (bsg also takes a ref to a queue, but it\ndoesn\u0027t prevent the device from going away).\n\nWith this patch, bsg increases the refcount of struct device in\nfops-\u003eopen and decreases it in fops-\u003erelease.\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n" }, { "commit": "93de00fd1c70e1a23a73a865e0f9abfe74a7a719", "tree": "44a0112d29bc82bb619fe4b0437a64fd92620968", "parents": [ "9a0e77f28b50128df0c9e26ae489e44e29a7270a" ], "author": { "name": "Bartlomiej Zolnierkiewicz", "email": "bzolnier@gmail.com", "time": "Fri Apr 18 00:46:24 2008 +0200" }, "committer": { "name": "Bartlomiej Zolnierkiewicz", "email": "bzolnier@gmail.com", "time": "Fri Apr 18 00:46:24 2008 +0200" }, "message": "ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3)\n\nhdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS\nand given the number of bugs we can assume that there are no real users:\n\n* DMA has no chance of working because DMA resources are released by\n ide_unregister() and they are never allocated again.\n\n* Since ide_init_hwif_ports() is used for -\u003eio_ports[] setup the ioctls\n don\u0027t work for almost all hosts with \"non-standard\" (\u003d\u003d non ISA-like)\n layout of IDE taskfile registers (there is a lot of such host drivers).\n\n* ide_port_init_devices() is not called when probing IDE devices so:\n -
