To get this data, currently one has to\n also enable CONFIG_DEBUG_CFQ_IOSCHED, which in turn brings the overhead of\n all the additional debug stat files which is not desired.\n\n Hence, this patch moves printing of cgroup paths under\n CONFIG_CFQ_GROUP_IOSCHED.\n\n This allows us to get rid of CONFIG_DEBUG_CFQ_IOSCHED completely. Now all\n the debug stat files are controlled only by CONFIG_DEBUG_BLK_CGROUP which\n can be enabled through config menu.\n\nSigned-off-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nAcked-by: Divyesh Shah \u003cdpshah@google.com\u003e\nReviewed-by: Gui Jianfeng \u003cguijianfeng@cn.fujitsu.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "67523c48aa74d5637848edeccf285af1c60bf14a", "tree": "ebd14992e210c8dfb503ae5fdffc1f5392ad52df", "parents": [ "8ca712ea84728531d36841ca8f98f9e8680bcf4e" ], "author": { "name": "Ben Blum", "email": "bblum@andrew.cmu.edu", "time": "Wed Mar 10 15:22:11 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 12 15:52:36 2010 -0800" }, "message": "cgroups: blkio subsystem as module\n\nModify the Block I/O cgroup subsystem to be able to be built as a module.\nAs the CFQ disk scheduler optionally depends on blk-cgroup, config options\nin block/Kconfig, block/Kconfig.iosched, and block/blk-cgroup.h are\nenhanced to support the new module dependency.\n\nSigned-off-by: Ben Blum \u003cbblum@andrew.cmu.edu\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: \"David S.

Not all embedded devices require\nit, some can make do with just JFFS2, NFS, ramfs, etc - none of which require\nthe block layer to be present.\n\nThis patch does the following:\n\n (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev\n support.\n\n (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls\n an item that uses the block layer. This includes:\n\n (*) Block I/O tracing.\n\n (*) Disk partition code.\n\n (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.\n\n (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the\n \t block layer to do scheduling. Some drivers that use SCSI facilities -\n \t such as USB storage - end up disabled indirectly from this.\n\n (*) Various block-based device drivers, such as IDE and the old CDROM\n \t drivers.\n\n (*) MTD blockdev handling and FTL.\n\n (*) JFFS - which uses set_bdev_super(), something it could avoid doing by\n \t taking a leaf out of JFFS2\u0027s book.\n\n (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and\n linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,\n however, still used in places, and so is still available.\n\n (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and\n parts of linux/fs.h.\n\n (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.\n\n (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.\n\n (*) set_page_dirty() doesn\u0027t call __set_page_dirty_buffers() if CONFIG_BLOCK\n is not enabled.\n\n (*) fs/no-block.c is created to hold out-of-line stubs and things that are\n required when CONFIG_BLOCK is not set:\n\n (*) Default blockdev file operations (to give error ENODEV on opening).\n\n (*) Makes some /proc changes:\n\n (*) /proc/devices does not list any blockdevs.\n\n (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.\n\n (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.\n\n (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if\n given command other than Q_SYNC or if a special device is specified.\n\n (*) In init/do_mounts.c, no reference is made to the blockdev routines if\n CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.\n\n (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return\n error ENOSYS by way of cond_syscall if so).\n\n (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if\n CONFIG_BLOCK is not set, since they can\u0027t then happen.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "b17fd9bceb99610f6dc7998c9a4ed6b71520be2b", "tree": "13cb21955ce4677360c72f7120fee311f16ca3c7", "parents": [ "8f34ee75decb80007ba77bba5a7384eadff4866d" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Mon Jun 19 10:06:48 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Fri Jun 23 17:10:39 2006 +0200" }, "message": "[PATCH] Make CFQ the default IO scheduler\n\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "c6ea2ba7b8acdb6c4a883b2d38607c8078dff4ee", "tree": "d175d3c28c0ff28cee62a4073c48f96b029cacab", "parents": [ "3a65dfe8c088143c7155cfd36a72f4b0ad2fc4b2" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Fri Nov 04 08:44:58 2005 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Fri Nov 04 08:44:58 2005 +0100" }, "message": "[BLOCK] iosched: fix setting of default io scheduler\n\nWith the recent reorg of the io scheduler selection, it unfortunately\nbecame possible to select an io scheduler to be the default even if it\nwasn\u0027t builtin.
