Linux kernel source tree
2aab4b355c
If a KVM selftest is run on a machine without /dev/kvm, it will exit silently. Make it easy to tell what's happening by printing an error message. Opportunistically consolidate all codepaths that open /dev/kvm into a single function so they all print the same message. This slightly changes the semantics of vm_is_unrestricted_guest() by changing a TEST_ASSERT() to exit(KSFT_SKIP). However vm_is_unrestricted_guest() is only called in one place (x86_64/mmio_warning_test.c) and that is to determine if the test should be skipped or not.

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.
