Add control command of UBLK_U_CMD_GET_FEATURES for returning driver's feature set or capability. This way can simplify userspace for maintaining compatibility because userspace doesn't need to send command to one device for querying driver feature set any more. Such as, with the queried feature set, userspace can choose to use: - UBLK_CMD_GET_DEV_INFO2 or UBLK_CMD_GET_DEV_INFO, - UBLK_U_CMD_* or UBLK_CMD_* Userspace code: https://github.com/ming1/ubdsrv/commits/features-cmd Signed-off-by: Ming Lei <ming.lei@redhat.com> Link: https://lore.kernel.org/r/20230603040601.775227-1-ming.lei@redhat.com Signed-off-by: Jens Axboe <axboe@kernel.dk> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
