[ Upstream commit 2d65fc13be85c336c56af7077f08ccd3a3a15a4a ] When compiling with clang (19.1.7), initializing *vp using a compound literal may result in excessive stack usage. Fix it by initializing the required fields of *vp individually. Without this patch: $ objdump -d arch/um/drivers/vector_kern.o | ./scripts/checkstack.pl x86_64 0 ... 0x0000000000000540 vector_eth_configure [vector_kern.o]:1472 ...

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.
