Colin Ian King ec132ef2d1 dm clone: make array 'descs' static
Don't populate the read-only array descs on the stack but instead it
static and add extra const. Also makes the object code smaller by 66
bytes:

Before:
   text    data     bss     dec     hex filename
  42382   11140     512   54034    d312 ./drivers/md/dm-clone-target.o

After:
   text    data     bss     dec     hex filename
  42220   11236     512   53968    d2d0 ./drivers/md/dm-clone-target.o

(gcc version 11.2.0)

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.
