Those particular headers only do anything when you're compiling. For
runtime stuff, they don't even need to be there. However, they _should_
be from the version of the kernel that was being used when glibc was
built. (I.e., you don't upgrade those things when you upgrade the
In any case, diff the two and you'll see remarkably little difference
Before you go to all that trouble (and after you've made sure your
.config file from 2.4.20 and your .config from 2.4.21 match up), just
rebuild your RAID tools. It's more likely that the kernel change upset
them than it is that there's something up with glibc.
