Allow a block device to allocate and register an integrity profile
without providing a template. This allows DM to preallocate a profile
to avoid deadlocks during table reconfiguration.Signed-off-by: Martin K. Petersen

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

- kobject_del already puts the parent.
- Set integrity profile to NULL to prevent stale data.

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

…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.

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.
