NFSD: Reading a fault injection file prints a state count
I also log basic information that I can figure out about the type of state (such as number of locks for each client IP address). This can be useful for checking that state was actually dropped and later for checking if the client was able to recover. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: J.
