[PATCH 003 of 20] knfsd: nfsd4: store pseudoflavor in request

From: NeilBrown
Date: Mon Jul 09 2007 - 22:23:44 EST



From: andros@xxxxxxxxxxxxxx <andros@xxxxxxxxxxxxxx>

Add a new field to the svc_rqst structure to record the pseudoflavor that
the request was made with. For now we record the pseudoflavor but don't
use it for anything.
