NAME

       kpatch-build - build script

SYNOPSIS

       kpatch-build [options] <patch file>

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.

OPTIONS

       -h|--help
          Show this help message

       -a|--archversion
          Specify the kernel arch version

       -r|--sourcerpm
          Specify kernel source RPM

       -s|--sourcedir
          Specify kernel source directory

       -c|--config
          Specify kernel config file

       -v|--vmlinux
          Specify original vmlinux

       -j|--jobs
          Specify the number of make jobs

       -t|--target
          Specify custom kernel build targets

       -n|--name
          Specify the name of the kpatch module

       -o|--output
          Specify output folder

       -d|--debug
          Keep scratch files in /tmp
          (can be specified multiple times)

       -e|--oot-module
          Enable patching out-of-tree module,
          specify current version of module

       --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.
