[OpenAFS-devel] Fully Functional Client on Linux 2.6

[Jack Neely]

Folks,

I have a fully functional OpenAFS client on Linux 2.6, well, at least
the current Fedora Core 2 kernels.  I decided to document NCSU's OpenAFS
packages a bit.  That includes this information and is at:

    http://linux.ncsu.edu/projects/openafs-rpms/

You'll need to have both kernel and kernel-smp packages installed to
build the RPM from there.

The current set of patches against yesterday's CVS (pretty much 1.3.65)
are attached.
