block: Switch blk_integrity_compare from bdev to gendisk

2008-10-09T06:56:21+00:00

The DM and MD integrity support now depends on being able to use gendisks instead of block_devices when comparing integrity profiles. Change function parameters accordingly. Also update comparison logic so that two NULL profiles are a valid configuration. Signed-off-by: Martin K. Petersen Signed-off-by: Jens Axboe

block: Fix double put in blk_integrity_unregister

2008-10-09T06:56:21+00:00

- kobject_del already puts the parent. - Set integrity profile to NULL to prevent stale data. Signed-off-by: Martin K. Petersen Signed-off-by: Jens Axboe

block: implement and use {disk|part}_to_dev()

2008-10-09T06:56:07+00:00

Implement {disk|part}_to_dev() and use them to access generic device instead of directly dereferencing {disk|part}->dev. To make sure no user is left behind, rename generic devices fields to __dev. This is in preparation of unifying partition 0 handling with other partitions. Signed-off-by: Tejun Heo Signed-off-by: Jens Axboe

Add some block/ source files to the kernel-api docbook. Fix kernel-doc notation in them as needed. Fix changed function parameter names. Fix typos/spellos. In comments, change REQ_SPECIAL to REQ_TYPE_SPECIAL and REQ_BLOCK_PC to REQ_TYPE_BLOCK_PC.

block: integrity flags can't use bit ops on unsigned short

2008-07-03T11:21:15+00:00

Just use normal open coded bit operations instead, they need not be atomic. Signed-off-by: Jens Axboe

block: integrity checkpatch cleanups

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
