[PATCH 0/3] cifs.upcall: small cleanups for cifs.upcall program (try #2)

[Jeff Layton]

This patchset comprises a number of cleanups for the cifs upcall
binary. The biggest change is that it renames it from cifs.spnego
to cifs.upcall since the cifs.spnego name really isn't applicable
anymore.

It also fixes a segfault when the program is run without any args
and adds a manpage. Comments and/or suggestions appreciated.

This set should apply cleanly to the 3.3 test branch.
