Hello XFS team, In order to make XFS work on Redhat Enterprise Linux 4, using the stock RH largesmp kernel (our server has 16 CPU's) I had to adapt the spec file for the kernel-module-xfs source rpm you offer for download at ftp://oss.sgi.com/projects/xfs/download/testing/RHEL4/kernel-module-xfs-2.6.9-22.EL-0.1-1.src.rpm The issue is that largesmp was not recognized as a kernel type, and with the original specfile an RPM was build with a dependency "requires kernel-smp = 2.6.9-67.0.1.ELlarge" where the dependency should have been "requires kernel-largesmp = 2.6.9-67.0.1". The fix was to add "largesmp" to the list of defined kernel_type at the top of the .spec file. I also fixed a typo in this list (default instead of deault). The new fixed spec file (kernel-module-xfs.spec), the original spec file (kernel-module-xfs.spec.orig) and a diff between the two (kernel-module-xfs.spec.patch are attached to this email. For other users, it might be useful to include this in the next release.
