Fedora 34: 2021-d56567bdab Moderate: Kernel Headers System Fixes

Kernel-headers includes the C header files that specify the interface

between the Linux kernel and userspace libraries and programs. The

header files define structures and constants that are needed for

building most standard programs and are also needed for rebuilding the

glibc package.

The 5.11.14 stable kernel update contains a number of important fixes across the

tree.
