pass a struct block_device to the blk-crypto interfaces v3

pass a struct block_device to the blk-crypto interfaces v3

[Christoph Hellwig]

Hi all,

this series switches the blk-crypto interfaces to take block_device
arguments instead of request_queues, and with that finishes off the
project to hide struct request_queue from file systems.

Changes since v2:
 - update a few comments
 - fix a whitespace error
 - remove now unused forward declarations
 - fix spelling errors an not precise enough wording in commit messages
 - move a few more declarations around inside or between headers

Changes since v1:
 - keep using request_queue in the Documentation for driver interfaces
 - rename to blk_crypto_cfg_supported to
   blk_crypto_config_supported_natively and move it to blk-crypto.[ch]
 - mark __blk_crypto_cfg_supported private

[PATCH 1/3] blk-crypto: don't use struct request_queue for public interfaces

[Christoph Hellwig]

Switch all public blk-crypto interfaces to use struct block_device
arguments to specify the device they operate on instead of th
request_queue, which is a block layer implementation detail.

[PATCH 2/3] blk-crypto: add a blk_crypto_config_supported_natively helper

[Christoph Hellwig]

Add a blk_crypto_config_supported_natively helper that wraps
__blk_crypto_cfg_supported to retrieve the crypto_profile from the
request queue.  With this fscrypt can stop including
blk-crypto-profile.h and rely on the public consumer interface in
blk-crypto.h.
