Subject[regression] NFS readdir change break fully cached nfs root

My NFS root test systems stopped booting with 2.6.37-rc1. It just
hangs after entering user space.

The NFS root setup uses a slightly fancy parameter setup to minimize
network traffic:

nfsroot=,nocto,acregmin=86400,acregmax=86400,acdirmin=86400,acdirmax=86400 root=/dev/nfs

I bisected it down to this commit from Bryan.

Unfortunately it's not trivially revertable because that conflicts
with later patches.
