Hey, let's give it a whirl. No promises, but please do let me know how it works out. I've also sent this out to the linux-xfs list.

################################################################# # # # NOTICE # # This xfs module rpm has been provided for testing purposes # # only. It is believed to be functional, but it has not been # # heavily tested. In particular, you may have issues with the # # 4KSTACKS option on RHEL4 ia32 kernels, depending on your IO # # hardware, layering, nfs usage, etc. # # # # Please do NOT report any problems with this module, or with # # the kernel when this module is loaded, to Red Hat. # # You may report issues to the linux-xfs@oss.sgi.com list. # # (Please also report successes!) # # # #################################################################
To rebuild, do something like this:
rpmbuild --rebuild --target i686 --define "kernel_topdir /lib/modules/2.6.9-22.EL/build" kernel-module-xfs-2.6.9-22.EL-0.1-1.src.rpm
where the --target should match your architecture (actually not needed for x86_64 or ia64, it just affects the rpm name), and the kernel_topdir is /lib/modules/`uname -r`/build for the RHEL4 kernel you wish to build against.
I have tested this xfs codebase a little bit with the xfs qa tests from xfs-cmds cvs with the 2.6.9-22.ELsmp kernel on ia32. It should work on other architectures and flavors (bigmem, non-smp, etc), and it may work with other RHEL4 kernel versions, but no guarantees on that.
