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.

For this the driver\nuses page_address() which is broken on highmem. Apart from this the\nactual calculation of the virtual address is wrong (even without highmem).\nSo, e.g., for reading it reads bytes from the driver to a wrong address\nand returns wrong data, I guess, for writing it would just output random\ndata to the device.\n\nThe proper fix, as suggested by many, is to dynamically map data using\nkmap_atomic(page, KM_BIO_SRC_IRQ) / kunmap_atomic(virt). The reason why it\nhas not been done until now, although I\u0027ve done some preliminary patches\nmore than a year ago was that nobody interested in fixing this problem was\nable to reliably reproduce it. Now it changed - with the help from\nSebastian Frei (CC\u0027ed) I was able to trigger the PIO path. Thus, I was\nalso able to test and debug it.\n\nThere are 4 cases when PIO is used in dc395x - data-in / -out with and\nwithout scatter-gather. I was able to reproduce and test only data-in with\nand without SG. So, the data-out path is still untested, but it is also\nsomewhat simpler than the data-in. Fredrik Roubert (also CC\u0027ed) also had\nPIO triggering on his system, and in his case it was data-out without SG.\nIt would be great if he could test the attached patch on his system, but\neven if he cannot, I would still request to apply the patch and just wait\nif anybody cries...\n\nImplementation: I put 2 new functions in scsi_lib.c and their declarations\nin scsi_cmnd.h. I exported them without _GPL, although, I don\u0027t feel\nstrongly about that - not many drivers are likely to use them. But there\nis at least one more - I want to use them in tmscsim.c. Whether these are\nthe right files for the functions and their declarations - not sure\neither. Actually, they are not scsi-specific, so, might go somewhere\naround other scattergather magic? They are not platform specific either,\nand most SG functions are defined under arch/*/... As these issues were\ndiscussed previously there were some more routines suggested to manipulate\nscattergather buffers, I think, some of them were needed around\ncrypto code... So, might be a common place reasonable, like\nlib/scattergather.c?
