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": "5404bc7a87b9949cf61e0174b21f80e73239ab25", "tree": "230c799aef2dcad8c64da55114508d28d2b30183", "parents": [ "da20a20f3b5c175648fa797c899dd577e4dacb51" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Thu Aug 10 09:01:02 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:29:42 2006 +0200" }, "message": "[PATCH] Allow file systems to differentiate between data and meta reads\n\nWe can use this information for making more intelligent priority\ndecisions, and it will also be useful for blktrace.\n\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "dc72ef4ae35c2016fb594bcc85ce871376682174", "tree": "c0c78879addf0d65adcc8f8cce01165fa2502dac", "parents": [ "981a79730d586335ef8f942c83bdf2b1de6d4e3d" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Thu Jul 20 14:54:05 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:29:40 2006 +0200" }, "message": "[PATCH] Add blk_start_queueing() helper\n\nCFQ implements this on its own now, but it\u0027s really block layer\nknowledge.

This patch assumes generic\ndispatch queue patchset is applied.\n\n * Each request is tagged with REQ_ELVPRIV flag if it has its elevator\n private data set.\n * Requests which doesn\u0027t have REQ_ELVPRIV flag set never enter\n iosched. They are always directly back inserted to dispatch queue.\n Of course, elevator_put_req_fn is called only for requests which\n have its REQ_ELVPRIV set.\n * Request queue maintains the current number of requests which have\n its elevator data set (elevator_set_req_fn called) in\n q-\u003erq-\u003eelvpriv.\n * If a request queue has QUEUE_FLAG_BYPASS set, elevator private data\n is not allocated for new requests.\n\n To switch to another iosched, we set QUEUE_FLAG_BYPASS and wait until\nelvpriv goes to zero; then, we attach the new iosched and clears\nQUEUE_FLAG_BYPASS. New implementation is much simpler and main code\npaths are less cluttered, IMHO.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "cb19833dccb32f97cacbfff834b53523915f13f6", "tree": "24fb8d125bcfdf5209ac6f502b78160d0193428c", "parents": [ "4c9f7836406f41ef9da6ee68d7a0448fdb97b5ef" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Mon Oct 24 08:35:58 2005 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Fri Oct 28 08:46:01 2005 +0200" }, "message": "[BLOCK] kill generic max_back_kb handling\n\nThis patch kills max_back_kb handling from elv_dispatch_sort() and\nkills max_back_kb field from struct request_queue.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "06b86245c052963029bfd9020ca1f08ceb66f85a", "tree": "1bd2675aceca74398f5fcf148f6cf2f551d63b52", "parents": [ "b4878f245ec8e168cdd1f170f823a750b7dd4af5" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Thu Oct 20 16:46:23 2005 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Fri Oct 28 08:45:20 2005 +0200" }, "message": "[PATCH] 03/05 move last_merge handlin into generic elevator code\n\nCurrently, both generic elevator code and specific ioscheds\nparticipate in the management and usage of last_merge.
