%description
kpatch is a Linux dynamic kernel patching infrastructure 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, for users to log off, or for scheduled reboot
windows. It gives more control over uptime without sacrificing security or stability.
