Just add another argument to your call ;-)

my_device.FilesystemCreate.begin ("reiserfs",null, () => {
        // do whatever you want when the operation is finished
});

see http://live.gnome.org/Vala/Tutorial#Asynchronous_Methods

(and btw, I think you can use vala-ish method name filesystem_create and
valac will correctly translate it).

HTH,
