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

2009-08-16T21:18:27+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. Signed-off-by: John Stoffel Signed-off-by: Jens Axboe Signed-off-by: Greg Kroah-Hartman

blktrace: the ftrace interface needs CONFIG_TRACING

2009-01-27T13:30:36+00:00

Impact: build fix Also mention in the help text that blktrace now can be used using the ftrace interface. Reported-by: Ingo Molnar Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar

Get rid of CONFIG_LSF

2008-12-29T07:29:51+00:00

We have two seperate config entries for large devices/files. One is CONFIG_LBD that guards just the devices, the other is CONFIG_LSF that handles large files. This doesn't make a lot of sense, you typically want both or none. So get rid of CONFIG_LSF and change CONFIG_LBD wording to indicate that it covers both.

blktrace: port to tracepoints

2008-11-26T11:13:34+00:00

This was a forward port of work done by Mathieu Desnoyers, I changed it to encode the 'what' parameter on the tracepoint name, so that one can register interest in specific events and not on classes of events to then check the 'what' parameter.

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. Signed-off-by: Martin K. Petersen Signed-off-by: Jens Axboe

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. Signed-off-by: Nick Andrew Cc: "Randy.Dunlap" Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe

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. Signed-off-by: Linus Torvalds
