I must admit that I'm quite confused by the commit you're referring to.
In which tree is it ?

Anyway, this problem has already been fixed in the latest version of
the patch I sent to LKML on August, 4th:
http://marc.info/?l=linux-kernel&m=121802891417797&w=2

However, I just sent another fixup patch to LKML, required to get NFS
server to compile with CONFIG_FILE_LOCKING=n. For reference, I copy it
below.

Sincerly,

Thomas

Fixup configure out fs locks support

This patch adds a few more stubs required to get NFS server to compile
properly with CONFIG_FILE_LOCKING=n.
