Make SCSI SG v4 driver enabled by default and remove EXPERIMENTAL dependency, since udev depends on BSG

2009-08-16T21:26:33+00:00

commit 14d9fa352592582e457cf75022202766baac1348 upstream.

Make Block Layer SG support v4 the default, since recent udev versions
depend on this to access serial numbers and other low level info properly.

This should be backported to older kernels as well, since most distros have
enabled this for a long time.

block: Block layer data integrity support

2008-07-03T11:21:13+00:00

Some block devices support verifying the integrity of requests by way
of checksums or other protection information that is submitted along
with the I/O.

This patch implements support for generating and verifying integrity
metadata, as well as correctly merging, splitting and cloning bios and
requests that have this extra information attached.

See Documentation/block/data-integrity.txt for more information.

Kconfig: clean up block/Kconfig help descriptions

2008-04-21T07:51:04+00:00

Modify the help descriptions of block/Kconfig for clarity, accuracy and
consistency.

Refactor the BLOCK description a bit.  The wording "This permits ...  to be
removed" isn't quite right; the block layer is removed when the option is
disabled, whereas most descriptions talk about what happens when the option is
enabled.  Reformat the list of what is affected by disabling the block layer.

Add more examples of large block devices to LBD and strive for technical
accuracy; block devices of size _exactly_ 2TB require CONFIG_LBD, not only
"bigger than 2TB".  Also try to say (perhaps not very clearly) that the config
option is only needed when you want to have individual block devices of size
>= 2TB, for example if you had 3 x 1TB disks in your computer you'd have a
total storage size of 3TB but you wouldn't need the option unless you want to
aggregate those disks into a RAID or LVM.

Improve terminology and grammar on BLK_DEV_IO_TRACE.

I also added the boilerplate "If unsure, say N" to most options.

Precisely say "2TB and larger" for LSF.

Indent the help text for BLK_DEV_BSG by 2 spaces in accordance with the
standard.

Only enable BLOCK_COMPAT if COMPAT is needed

2007-10-13T00:58:36+00:00

IOW, it needs to depend on both CONFIG_BLOCK and CONFIG_COMPAT.

[BLOCK] Only include the compat ioctl code if CONFIG_BLOCK is set

Add an extra CONFIG_BLOCK_COMPAT that we can use in the Makefile

bsg: Fix build for CONFIG_BLOCK=n

2007-07-27T06:08:24+00:00

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)

2007-07-19T17:37:34+00:00

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).

Make BLK_DEV_BSG depend strictly on SCSI=y

2007-07-16T23:53:22+00:00

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.
