Now that you pointed me to it (thanks!), I found it:
I think your summary is correct, but I'd add one BIG modification: 4kstacks
only affects i386 (including e.g. i686) arches. For example, the arch I use,
x86_64, still uses 8k stacks, so I only need to add CONFIG_XFS_FS. I've
verified this to my satisfaction by looking at the RHEL4 kernel source, but
also see Andi Kleen's post to the above thread:
ONE MORE question or set of questions. :)
So now I've got my RHEL4 kernel source tree, which is based on 2.6.9 and
appears to have no patches to xfs (with the possible exception of patches
outside the xfs/ tree that affect xfs). Would it be advisable to just use
this version, or to try to update the xfs kernel code in some way (replace
the xfs/ tree with the 2.6.11 version? apply some patches?)? I see that the
xfs patches kept coming in for 2.6.10 and 2.6.11.
