Description:
Runtime tools for Kpatch
kpatch is a Linux dynamic kernel patching tool which allows you to patch a running kernel without rebooting or restarting any processes. It enables sysadmins to apply critical security patches to the kernel immediately, without having to wait for long-running tasks to complete, users to log off, or for scheduled reboot windows. It gives more control over up-time without sacrificing security or stability.
