The xfs kernel modules at dev.centos.org are very handy. There are a
couple of xfs modules in the 4.3 x86_64 directory, but I don't think
it's for the x86_64 4.3 kernel (2.6.9-34). The latest ones in that
directory is for the -22 kernel (I believe this came with CentOS 4.2).
Get one of the kernel-module-xfs SRPMS (doesn't matter which one, they
are the same), install it and then edit the kernel-module-xfs.spec
file and comment out the line:
%patch6 -p1
(or, use the patch to the spec file attached)
and then build the RPM using something like:
rpmbuild --target x86_64 --define "kernel_topdir /lib/modules/2.6.9-34/build" \
kernel-module-xfs.spec
see: ftp://oss.sgi.com/projects/xfs/testing/RHEL4/README
I was given these instructions by Eric Sandeen @ SGI
I've been using 2.6.9-34 with XFS compiled in this way ...

Dang ... did I not publish those?
I will check now, and if they are not published, then I will do so.
OK ... should be some good xfs kernel modules for all the kernels now.
The spec file still applies %patch6 for the 2.6.9-34 kernels - I was
under the impression that this patch was not needed with the RHEL4U3
(and above) kernels ... although this may now not be the case.
It works this way, though if upstream has properly patched up fs/direct-
io.c it may no longer be required.
I have contacted SGI and asked for any other mods that they might have
too.
If they give me any, I'll rebuild the modules.
Thanks for the input ...
This is from an email from Eric Sandeen:
I put this blurb into the spec so it will build against both eras of EL4
kernels:
# Updated dio locking scheme appeared in RHEL4U3; so did
DIO_CLUSTER_LOCKING,
# which we can use as a marker.
# (actual changes we need were in direct-io.c, it's not in kernel-dev
package)
# "older_dio_locking" is then 1 if we're building against an un-updated
kernel
%define older_dio_locking %(grep -q DIO_CLUSTER_LOCKING
%{kernel_topdir}/include/linux/fs.h; echo $?)
and then wrapped the proper patch:
Patch6 : xfs_direct_io_locking.patch
...
%if %{older_dio_locking}
%patch6 -p1
%endif
I included this as a patch to the spec file eariler in this thread
