Re: [PATCH v3 2/2] nbd: Add testsuite coverage

[Jose E. Marchesi]

    +Using NBD connections in tests
    +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    +
    +If your test requires an NBD server (only useful when poke is compiled
    +with libnbd), the dg-nbd directive is what you need.  It has one form::
    +
    +  /* { dg-nbd { 0x1 0x2 ...} [dg-tmpdir]/sock } */
    +
    +This utilizes nbdkit to serve an in-memory disk with initial contents
    +over a named Unix socket.  Note that the data argument is not written
    +in Poke, but rather the syntax accepted by nbdkit-data-plugin's data=
    +argument.

The syntax used in dg-data is not actually Poke.  It is the format
argument expected by the binary(3tcl) command.

Other than that, the patch is OK for master.
Thanks! :)
