The\nlookup itself is an O(N) list lookup, where N is the number of\npartitions. This actually hurts performance quite a bit, even\non the lower end partitions. On higher numbered partitions,\nit can get pretty bad.\n\nSolve this by adding a one-hit cache for partition lookup.\nThis makes the lookup O(1) for the case where we do most IO to\none partition. Even for mixed partition workloads, amortized cost\nis pretty close to O(1) since the natural IO batching makes the\none-hit cache last for lots of IOs.\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "bf91db18ac2852a3ff39fe25ff56c5557c0fff78", "tree": "42ce67fceb2b3072717cde31c8b4474f4c4a050d", "parents": [ "53cc0b2948bcb8a084982e6c1f9bd7b337e0df38" ], "author": { "name": "Cheng Renquan", "email": "crquan@gmail.com", "time": "Thu Nov 20 08:37:37 2008 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Wed Dec 03 12:41:20 2008 +0100" }, "message": "block: set disk-\u003enode_id before it\u0027s being used\n\ndisk-\u003enode_id will be refered in allocating in disk_expand_part_tbl, so we\nshould set it before disk-\u003enode_id is refered.\n\nSigned-off-by: Cheng Renquan \u003ccrquan@gmail.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "561ec68e4de7947167937c49c451728e6b19e63b", "tree": "4391af5bc00e5a2039e703df43ec3e84a21b63d5", "parents": [ "55e8e30c382d25c34f8aafcc78efec948571a941" ], "author": { "name": "Zhang, Yanmin", "email": "yanmin_zhang@linux.intel.com", "time": "Fri Nov 14 08:26:30 2008 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Nov 18 15:08:56 2008 +0100" }, "message": "block: fix boot failure with CONFIG_DEBUG_BLOCK_EXT_DEVT\u003dy and nash\n\nWe run into system boot failure with kernel 2.6.28-rc. We found it on a\ncouple of machines, including T61 notebook, nehalem machine, and another\nHPC NX6325 notebook. All the machines use FedoraCore 8 or FedoraCore 9.\nWith kernel prior to 2.6.28-rc, system boot doesn\u0027t fail.\n\nI debug it and locate the root cause. Pls. see\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d11899\nhttps://bugzilla.redhat.com/show_bug.cgi?id\u003d471517\n\nAs a matter of fact, there are 2 bugs.\n\n1)root\u003d/dev/sda1, system boot randomly fails. Mostly, boot for 5 times\nand fails once. nash has a bug. Some of its functions misuse return\nvalue 0. Sometimes, 0 means timeout and no uevent available. Sometimes,\n0 means nash gets an uevent, but the uevent isn\u0027t block-related (for\nexmaple, usb). If by coincidence, kernel tells nash that uevents are\navailable, but kernel also set timeout, nash might stops collecting\nother uevents in queue if current uevent isn\u0027t block-related. I work\nout a patch for nash to fix it.\nhttp://bugzilla.kernel.org/attachment.cgi?id\u003d18858\n\n2) root\u003dLABEL\u003d/, system always can\u0027t boot. initrd init reports\nswitchroot fails. Here is an executation branch of nash when booting:\n (1) nash read /sys/block/sda/dev; Assume major is 8 (on my desktop)\n (2) nash query /proc/devices with the major number; It found line\n\t\"8 sd\";\n (3) nash use \u0027sd\u0027 to search its own probe table to find device (DISK)\n\ttype for the device and add it to its own list;\n (4) Later on, it probes all devices in its list to get filesystem\n\tlabels; scsi register \"8 sd\" always.\n\nWhen major is 259, nash fails to find the device(DISK) type. I enables\nCONFIG_DEBUG_BLOCK_EXT_DEVT\u003dy when compiling kernel, so 259 is picked up\nfor device /dev/sda1, which causes nash to fail to find device (DISK)\ntype.\n\nTo fixing issue 2), I create a patch for nash and another patch for\nkernel.\n\nhttp://bugzilla.kernel.org/attachment.cgi?id\u003d18859\nhttp://bugzilla.kernel.org/attachment.cgi?id\u003d18837\n\nBelow is the patch for kernel 2.6.28-rc4. It registers blkext, a new\nblock device in proc/devices.\n\nWith 2 patches on nash and 1 patch on kernel, I boot my machines for\ndozens of times without failure.\n\nSigned-off-by Zhang Yanmin \u003cyanmin.zhang@linux.intel.com\u003e\nAcked-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "31d85ab28e71b0c938e0ef48af45747e80d99b53", "tree": "1cd97bee97abb008dd3591da2a001e3e85356fb6", "parents": [ "5c9fe6281b75832e8d2555ec8700ea763d9a865e" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Oct 06 12:55:38 2008 +0400" }, "committer": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Thu Oct 23 17:57:37 2008 +0400" }, "message": "proc: move /proc/diskstats boilerplate to block/genhd.c\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "f500975a3f3ecf3611d79f1d933906753460b9f2", "tree": "df3728998ca1638ecbccf4ab6f401f9a2cbdba88", "parents": [ "8591cf43224980a0bc9216a4e50b0a740f8cba35" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Sat Oct 04 23:53:21 2008 +0400" }, "committer": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Thu Oct 23 15:07:31 2008 +0400" }, "message": "proc: move rest of /proc/partitions code to block/genhd.c\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "496aa8a98f5ab22ced46be5dc2087cdf3d029bd7", "tree": "5c4335ca12bbc8f93f7630c2ef0733973099cd17", "parents": [ "80a4b58e36b63d7b0b592beb1bd6410aadeeb63c" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Thu Oct 16 07:46:23 2008 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Fri Oct 17 08:46:57 2008 +0200" }, "message": "block: fix current kernel-doc warnings\n\nFix block kernel-doc warnings:\n\nWarning(linux-2.6.27-git4//fs/block_dev.c:1272): No description found for parameter \u0027path\u0027\nWarning(linux-2.6.27-git4//block/blk-core.c:1021): No description found for parameter \u0027cpu\u0027\nWarning(linux-2.6.27-git4//block/blk-core.c:1021): No description found for parameter \u0027part\u0027\nWarning(/var/linsrc/linux-2.6.27-git4//block/genhd.c:544): No description found for parameter \u0027partno\u0027\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "e6d63840ba55ffd3a79aea6792aac6f29f338083", "tree": "6fa14f4a89167e142385369a51e4d09f5c5233f8", "parents": [ "8677142710516d986d932d6f1fba7be8382c1fec" ], "author": { "name": "Li Zefan", "email": "lizf@cn.fujitsu.com", "time": "Tue Oct 14 08:49:34 2008 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Fri Oct 17 08:46:56 2008 +0200" }, "message": "block: fix kernel-doc for blk_alloc_devt()\n\nNo argument \u0027gfp_mask\u0027 for blk_alloc_devt().\n\nSigned-off-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "581d4e28d9195aa8b2231383dbabc288988d615e", "tree": "093bcac9a538ef67edcf91826f7532bdb88e6248", "parents": [ "0a0d96b03a1f3bfd6bc3ea08008699e8e59fccd9" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Sun Sep 14 05:56:33 2008 -0700" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu Oct 09 08:56:17 2008 +0200" }, "message": "block: add fault injection mechanism for faking request timeouts\n\nOnly works for the generic request timer handling.

However, when the numbers wrap on 64b platforms \u0026 you read the\nnumbers into unsigned longs, and compare the numbers to previous readings,\nthen you get an unsigned representation of a negative number.
