kpatch-build - build script
kpatch-build [options] <patch file>
This script takes a patch based on the version of the kernel currently running and creates a kernel module that will replace modified functions in the kernel such that the patched code takes effect.
This script currently only works on Fedora and will need to be adapted to work on other distros.

--skip-cleanup
Skip post-build cleanup
--skip-gcc-check
Skips check that ensures that the system gcc version and
the gcc version that built the kernel match. Skipping this
check is not recommended, but is useful if the exact gcc
version is not available or is not easily installed. Use
only when confident that the two versions of gcc output
identical objects for a given target. Otherwise, use of
this option might result in unexpected changed objects
being detected.
No known bugs.
