[OpenAFS-devel] bug building against RedHat 7.3 new kernel: 2.4.18-5

[Joe Little]

A major NFS v3 bug in RH7.3's kernel has brought about a new kernel from 
the company. At Stanford University, we build off of RedHat's release and 
distribute OpenAFS as a client. We have quickly jumped to OpenAFS 1.2.5, 
but the SRPM, which builds on kernel 2.4.18-4, fails to build on 2.4.18-5. 
It may have to do with other subtle changes in the new kernel (possibly 
scheduler changes)

Here is the pertinent failure section in the RPM build:

Has the maintainer of the RPM binaries on OpenAFS seen this yet? For us, 
the new kernel is a requirement since the old one happily takes down 
NetApps and Solaris boxes running NFS -- its not a 100% AFS world yet :)
