Documentation/block/request.rst is outdated and should be removed.
Also delete its entry in the block/index.rst file.

The capability attribute was added in 2017 to expose the kernel internal
GENHD_FL_MEDIA_CHANGE_NOTIFY to userspace without ever adding a value to
an UAPI header, and without ever setting it in any driver until it was
finally removed in Linux 5.7.
Deprecate the file and always return 0 instead of exposing the other
internal and frequently renumbered other gendisk flags.

Add documentation for ublk subsystem. It was supposed to be documented when
merging the driver, but missing at that time.

This document is completely out of date and extremely misleading. In
general the existing kerneldoc comment serve as a much better
documentation of the still existing functionality, while the history
blurbs are pretty much irrelevant today.

This has been replaced by Documentation/ABI/stable/sysfs-block, which is
the correct place for sysfs documentation.

Create a documentation providing a background and explanation around the
operation of the Multi-Queue Block IO Queueing Mechanism (blk-mq).
The reference for writing this documentation was the source code and
"Linux Block IO: Introducing Multi-queue SSD Access on Multi-core
Systems", by Axboe et al.

The blk-crypto framework adds support for inline encryption. There are
numerous changes throughout the storage stack. This patch documents the
main design choices in the block layer, the API presented to users of
the block layer (like fscrypt or layered devices) and the API presented
to drivers for adding support for inline encryption.

Those are subsystem docs, with a mix of kABI and user-faced
docs. While they're not split, keep the dirs where they are,
adding just a pointer to the main index.

Rename the block documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
