I've attached a patch which I believe will allow compilation on SuSE
systems. I don't actually have any, and my attempts at using kernel
headers extracted from SuSE rpms was not very successful, so I don't know
that it will work.... The kernel patches in question do not have to do
with large memory machine as much as supporting large files in the
filesystem. (needless to say, afs does not support large files, so my
patch did not actually add 64bit interfaces to afs, it merely extracts the
32 bit values it has always used.)
In addition, I also adjusted an AFS structure that needs to be kept in
sync with a linux struct inode. I would appreciate finding out if this
works for you so I can consider submitting it to the openafs-gatekeeper
(well, once I figure out how to identify LFS-patched kernels in a way
other than #ifdef _REISER_FS_I)
