[Qemu-devel] [PATCH v2 3/5] nbd: Use return values instead of error_is_set(errp)

[Markus Armbruster]

Using error_is_set(errp) to check whether a function call failed is
fragile: it breaks when errp is null.  Check perfectly suitable return
values instead when possible.  errp can't be null there now, but this
is more robust and more obviously correct
