bsg: Fix build for CONFIG_BLOCK=n

2007-07-27T06:08:24Z

BLK_DEV_BSG was added outside of the if BLOCK check, which allows it to be enabled when CONFIG_BLOCK=n. This leads to many screenlengths of errors, starting with a parse error on the request_queue_t definition. Obviously this wasn't intended for CONFIG_BLOCK=n usage, so just move the option back in to the block. Caught with a randconfig on sh.

[SCSI] bsg: separate bsg and SCSI (so SCSI can be modular)

2007-07-19T17:37:34Z

This patch moves the bsg registration into SCSI so that bsg no longer has a dependency on the scsi_interface_register API. This can be viewed as a temporary expedient until we can get universal bsg binding sorted out properly. Also use the sdev bus_id as the generic bsg name (to avoid clashes with the queue name).

bsg: Kconfig updates

Make BLK_DEV_BSG depend strictly on SCSI=y

2007-07-16T23:53:22Z

The SCSI code can be compiled modular, but BLK_DEV_BSG currently cannot, and depends on the SCSI layer. So make sure that it depends on the SCSI layer being compiled in, not just available as a module. Noticed by Jeff Garzik and S.Çağlar Onur.

bsg: Kconfig updates

This updates bsg entry in Kconfig: - bsg supports sg v4 - bsg depends on SCSI - it might be better to mark it experimental for a while Signed-off-by: FUJITA Tomonori Signed-off-by: Jens Axboe

[PATCH] Centralise definitions of sector_t and blkcnt_t

2006-12-05T03:41:15Z

CONFIG_LBD and CONFIG_LSF are spread into asm/types.h for no particularly good reason. Centralising the definition in linux/types.h means that arch maintainers don't need to bother adding it, as well as fixing the problem with x86-64 users being asked to make a decision that has absolutely no effect. The H8/300 porters seem particularly confused since I'm not aware of any microcontrollers that need to support 2TB filesystems. Signed-off-by: Matthew Wilcox Signed-off-by: Linus Torvalds

[PATCH] Only enable CONFIG_BLOCK option for embedded

It's too easy for people to shoot themselves in the foot, and it only makes sense for embedded folks anyway. Signed-off-by: Jens Axboe

[PATCH] BLOCK: Make it possible to disable the block layer [try #6]

2006-09-30T18:52:31Z

Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen. Signed-Off-By: David Howells Signed-off-by: Jens Axboe
