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": "4aff5e2333c9a1609662f2091f55c3f6fffdad36", "tree": "b73d8c2b7c1bdc03d3313c108da7dfc95ee95525", "parents": [ "77ed74da26f50fa28471571ee7a2251b77526d84" ], "author": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Thu Aug 10 08:44:47 2006 +0200" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:23:37 2006 +0200" }, "message": "[PATCH] Split struct request -\u003eflags into two parts\n\nRight now -\u003eflags is a bit of a mess: some are request types, and\nothers are just modifiers.

The functions cp and kjournald were blocked in did vary, but\nkmirrord\u0027s wchan always pointed to \u0027mempool_alloc()\u0027. We\u0027ve seen this pattern\non 2.6.15 and 2.6.17 kernels. http://lkml.org/lkml/2005/4/20/142 indicates\nthat this problem has been around even before.\n\nSo much for the facts, here\u0027s my interpretation: mempool_alloc() first tries\nto atomically allocate the requested memory, or falls back to hand out\npreallocated chunks from the mempool. If both fail, it puts the calling\nprocess (kmirrord in this case) on a private waitqueue until somebody refills\nthe pool. Where the only \u0027somebody\u0027 is kmirrord itself, so we have a\ndeadlock.\n\nI worked around this problem by falling back to a (blocking) kmalloc when\nbefore kmirrord would have ended up on the waitqueue. This defeats part of\nthe benefits of using the mempool, but at least keeps the system running. And\nit could be done with a two-line change. Note that mempool_alloc() clears the\nGFP_NOIO flag internally, and only uses it to decide whether to wait or return\nan error if immediate allocation fails, so the attached patch doesn\u0027t change\nbehaviour in the non-deadlocking case. Path is against current git\n(2.6.18-rc4), but should apply to earlier versions as well.

I don\u0027t believe this is a supportable\napproach.\n\nThis patch changes the approach to use the same approach as swap files. i.e.\nbmap is used to enumerate all the block address of parts of the file and we\nwrite directly to those blocks of the device.\n\nswapfile only uses parts of the file that provide a full pages at contiguous\naddresses. We don\u0027t have that luxury so we have to cope with pages that are\nnon-contiguous in storage. To handle this we attach buffers to each page, and\nstore the addresses in those buffers.\n\nWith this approach the pagecache may contain data which is inconsistent with\nwhat is on disk. To alleviate the problems this can cause, md invalidates the\npagecache when releasing the file. If the file is to be examined while the\narray is active (a non-critical but occasionally useful function), O_DIRECT io\nmust be used. And new version of mdadm will have support for this.\n\nThis approach simplifies a lot of code:\n - we no longer need to keep a list of pages which we need to wait for,\n as the b_endio function can keep track of how many outstanding\n writes there are. This saves a mempool.\n - -EAGAIN returns from write_page are no longer possible (not sure if\n they ever were actually).\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "acc55e220166a5ad898e66ad6153fd62eaaac76d", "tree": "c342dcd3303f01d97c5fe7718af9daf22ec086d2", "parents": [ "0cdd02cabd86b5d547f882005e23a93929f0ace9" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Mon Jun 26 00:27:47 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jun 26 09:58:38 2006 -0700" }, "message": "[PATCH] md/bitmap: tidy up i_writecount handling in md/bitmap\n\nmd/bitmap modifies i_writecount of a bitmap file to make sure that no-one else\nwrites to it.
