Documentation Kernel Beat
Fedora may include additional patches to the kernel for improvements, bug fixes, or additional features. For this reason, the Fedora kernel may not be line-for-line equivalent to the so-called vanilla kernel from the kernel.org web site at http://www.kernel.org.
To obtain a list of these patches, download the source RPM package and run the following command against it:
rpm -qpl kernel-<version>.src.rpm
To retrieve a log of changes to the package, run the following command:
rpm -q --changelog kernel-<version>
If you need a user friendly version of the changelog, refer to http://wiki.kernelnewbies.org/LinuxChanges. A short and full diff of the kernel is available from http://kernel.org/git. The Fedora version kernel is based on the Linus tree.
Customizations made for the Fedora version are available from http://cvs.fedoraproject.org.
Preparing for Kernel Development
Fedora 13 does not include the kernel-source package provided by older versions, since only the kernel-devel package is required now to build external modules.
Refer to http://kernel.org/pub/linux/docs/lkml/reporting-bugs.html for information on reporting bugs in the Linux kernel. You may also use http://bugzilla.redhat.com for reporting bugs that are specific to Fedora.
