/usr/src/linux-2.2.10/README.kernel-sources is included in both kernel-2.2.10-4 and kernel-headers-2.2.10-4. Causes rpm -V to complain, since the timestamps are different.
The README.kernel-sources file is included only in the kernel-headers package
$ rpm -q -f /usr/src/linux/README.kernel-sources kernel-headers-2.2.11-1 kernel-2.2.11-1
Ok, this is fixed in 2.2.11-4. You can go ahead and close the bug, sorry about that.
