block: move blk_exit_queue into disk_release

There can't be file system I/O in disk_release(), so move the call to
blk_exit_queue() there, preparing to have the teardown of file system I/O
only functionality in one place, when the gendisk that is needed for it
is torn down.

We still need to freeze queue here since the request is freed after the
bio is completed and passthrough request rely on scheduler tags as well.

The disk can be released before or after queue is cleaned up, and we have
to free the scheduler request pool before blk_cleanup_queue returns,
while the static request pool has to be freed before exiting the
I/O scheduler.

Merge tag 'v5.17-rc4' into for-linus

Merge with mainline to get the Intel ASoC generic helpers header and
other changes.

blk-crypto: show crypto capabilities in sysfs

Add sysfs files that expose the inline encryption capabilities of
request queues:

/sys/block/$disk/queue/crypto/max_dun_bits
/sys/block/$disk/queue/c

blk-crypto: show crypto capabilities in sysfs

Add sysfs files that expose the inline encryption capabilities of
request queues:

/sys/block/$disk/queue/crypto/max_dun_bits
/sys/block/$disk/queue/crypto/modes/$mode
/sys/block/$disk/queue/crypto/num_keyslots

Userspace can use these new files to decide what encryption settings to
use, or whether to use inline encryption at all. This also brings the
crypto capabilities in line with the other queue properties, which are
already discoverable via the queue directory in sysfs.

Design notes:

- Place the new files in a new subdirectory "crypto" to group them
together and to avoid complicating the main "queue" directory. This
also makes it possible to replace "crypto" with a symlink later if
we ever make the blk_crypto_profiles into real kobjects (see below).

- It was necessary to define a new kobject that corresponds to the
crypto subdirectory. For now, this kobject just contains a pointer
to the blk_crypto_profile. Note that multiple queues (and hence
multiple such kobjects) may refer to the same blk_crypto_profile.

An alternative design would more closely match the current kernel
data structures: the blk_crypto_profile could be a kobject itself,
located directly under the host controller device's kobject, while
/sys/block/$disk/queue/crypto would be a symlink to it.

I decided not to do that for now because it would require a lot more
changes, such as no longer embedding blk_crypto_profile in other
structures, and also because I'm not sure we can rule out moving the
crypto capabilities into 'struct queue_limits' in the future. (Even
if multiple queues share the same crypto engine, maybe the supported
data unit sizes could differ due to other queue properties.) It
would also still be possible to switch to that design later without
breaking userspace, by replacing the directory with a symlink.

- Use "max_dun_bits" instead of "max_dun_bytes". Currently, the
kernel internally stores this value in bytes, but that's an
implementation detail. It probably makes more sense to talk about
this value in bits, and choosing bits is more future-proof.

- "modes" is a sub-subdirectory, since there may be multiple supported
crypto modes, sysfs is supposed to have one value per file, and it
makes sense to group all the mode files together.

- Each mode had to be named. The crypto API names like "xts(aes)" are
not appropriate because they don't specify the key size. Therefore,
I assigned new names. The exact names chosen are arbitrary, but
they happen to match the names used in log messages in fs/crypto/.

- The "num_keyslots" file is a bit different from the others in that
it is only useful to know for performance reasons. However, it's
included as it can still be useful. For example, a user might not
want to use inline encryption if there aren't very many keyslots.

block: don't delete queue kobject before its children

kobjects aren't supposed to be deleted before their child kobjects are

triggered if one of the child kobjects has a named attribute group:

Fix this by moving the kobject_del() and the corresponding
kobject_uevent() to the correct place.
