Support referencing the root partition label from GPT as argument to the root= option on the kernel command line in analogy to referencing the partition uuid as root=PARTUUID=<uuid>. Specifying the partition label instead of the uuid is often much easier, e.g. in embedded environments when there is an A/B rootfs partition scheme for interruptible firmware updates (i.e. rootfsA/ rootfsB). The partition label can be queried with the blkid command.

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.
