For the recored here is the "crap" that's in FC1 and not in the stock
kernel:

From Trond's Tree:
linux-2.4.x-rdplus.dif
linux-2.4.x-cto.dif
linux-2.4.x-pathconf.dif

From -ac1 tree:
kmap() calls changed to kmap_atomic() calls

Patches posted to this list:
linux-2.4.21-nfs-accesscache.patch - reduces the number of otw
ACCESS calls
linux-2.4.20-nfs-ia64-EIO.patch - increase RPC_RTO_MIN to HZ/30

And here are the patches that are in the stock kernel
and not in FC1 (yet)...

# 03/10/11 trond.myklebust@fys.uio.no 1.1148.17.6
# Make the client act correctly if the RPC server's asserts
# that it does not support a given program, version or
# procedure call.

# 03/10/11 trond.myklebust@fys.uio.no 1.1148.17.1
# Fix a deadlock in the NFS asynchronous write code.
