Hmmm. The RedHat kernel does have a large file size patch - but it seems
only to be applied to the "enterprise" kernel - from the kernel RPM spec
file:
...
ApplyEnterprisePatches() {
# this is where we apply those patches that we *only* ship in the
# enterprise kernel
if [ %{lfs} -eq 1 -a %{ext3} -eq 1 ] ; then
echo "do not apply both lfs and ext3 at this time"
exit 1
fi
# Large File Summit (64bit file access) support
if [ %{lfs} -ne 0 ] ; then
patch -p1 < $RPM_SOURCE_DIR/linux-2.2.19-lfs.patch
# Only for use with BIGMEM
fi
...
If you have a test box, you might try the "enterprise" variant of the
kernel, and see what breaks. I know, for instance, that VMware doesn't
like some aspect of the "enterprise" kernel.
