[ Upstream commit 6e58e0173507e506a5627741358bc770f220e356 ] Commit13e1df0928("kheaders: explicitly validate existence of cpio command") added an explicit check for `cpio` using `type`. However, `type` in `dash` (which is used in some popular distributions and base images as the shell script runner) prints the missing message to standard output, and thus no error is printed: $ bash -c 'type missing >/dev/null' bash: line 1: type: missing: not found $ dash -c 'type missing >/dev/null' $ For instance, this issue may be seen by loongarch builders, given its defconfig enables CONFIG_IKHEADERS since commit 9cc1df421f00 ("LoongArch: Update Loongson-3 default config file"). Therefore, use `command -v` instead to have consistent behavior, and take the chance to provide a more explicit error.

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.
