A use case or two would be useful to explore (on linux-nfs or
linux-fsdevel, rather than lkml).
I created a bunch of use cases in the gensyscall.c program that
I attached to the original description of the problem and my
proposed solution. It was very useful in generating many, many
ESTALE errors over the wire from a variety of different over the
wire operations, which were originally getting returned to the
user level.
The gensyscall.c program is what I would call a set of unit test, btw.
This is not the same as a use case, which would include information
about the application environment, its users, a detailed description
of current system behavior, and some discussion of alternatives for
improving it (including doing nothing).
A test case is written in a programming language, a use case is
written in a natural language.
