.SH DESCRIPTION
|
|
|
|
|
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.

--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.
