Merge tag 'v6.1-rc2' into fixes

Merge rc2 into our fixes branch, which was based on rc1 but wasn't
merged until rc3, so that for the remainder of the release our fixes
branch will be based on rc2 for the purposes of resolving conflicts with
other trees (if necessary).

For retrieving device info via ``ublksrv_ctrl_dev_info``. It is the server's
responsibility to save IO target specific info in userspace.
- ``UBLK_CMD_START_USER_RECOVERY``
This command is valid if ``UBLK_F_USER_RECOVERY`` feature is enabled. This
command is accepted after the old process has exited, ublk device is quiesced
and ``/dev/ublkc*`` is released. User should send this command before he starts
a new process which re-opens ``/dev/ublkc*``. When this command returns, the
ublk device is ready for the new process.
- ``UBLK_CMD_END_USER_RECOVERY``
This command is valid if ``UBLK_F_USER_RECOVERY`` feature is enabled. This
command is accepted after ublk device is quiesced and a new process has
opened ``/dev/ublkc*`` and get all ublk queues be ready. When this command
returns, ublk device is unquiesced and new I/O requests are passed to the
new process.
- user recovery feature description
Two new features are added for user recovery: ``UBLK_F_USER_RECOVERY`` and
``UBLK_F_USER_RECOVERY_REISSUE``.
With ``UBLK_F_USER_RECOVERY`` set, after one ubq_daemon(ublk server's io
handler) is dying, ublk does not delete ``/dev/ublkb*`` during the whole
recovery stage and ublk device ID is kept. It is ublk server's
responsibility to recover the device context by its own knowledge.
Requests which have not been issued to userspace are requeued. Requests
which have been issued to userspace are aborted.
With ``UBLK_F_USER_RECOVERY_REISSUE`` set, after one ubq_daemon(ublk
server's io handler) is dying, contrary to ``UBLK_F_USER_RECOVERY``,
requests which have been issued to userspace are requeued and will be
re-issued to the new process after handling ``UBLK_CMD_END_USER_RECOVERY``.
``UBLK_F_USER_RECOVERY_REISSUE`` is designed for backends who tolerate
double-write since the driver may issue the same I/O request twice. It
might be useful to a read-only FS or a VM backend.

Pipelines and media streams
^^^^^^^^^^^^^^^^^^^^^^^^^^^
A media stream is a stream of pixels or metadata originating from one or more
source devices (such as a sensors) and flowing through media entity pads
towards the final sinks. The stream can be modified on the route by the
devices (e.g. scaling or pixel format conversions), or it can be split into
multiple branches, or multiple branches can be merged.
A media pipeline is a set of media streams which are interdependent. This
interdependency can be caused by the hardware (e.g. configuration of a second
stream cannot be changed if the first stream has been enabled) or by the driver
due to the software design. Most commonly a media pipeline consists of a single
stream which does not branch.
When starting streaming, drivers must notify all entities in the pipeline to
prevent link states from being modified during streaming by calling
:c:func:`media_pipeline_start()`.
The function will mark all entities connected to the given entity through
enabled links, either directly or indirectly, as streaming.
The function will mark all the pads which are part of the pipeline as streaming.
The struct media_pipeline instance pointed to by
the pipe argument will be stored in every entity in the pipeline.
the pipe argument will be stored in every pad in the pipeline.
Drivers should embed the struct media_pipeline
in higher-level pipeline structures and can then access the
pipeline through the struct media_entity
pipeline through the struct media_pad
pipe field.
Calls to :c:func:`media_pipeline_start()` can be nested.
