[kvm-unit-tests PATCH 8/8] lib: s390x: uv: Add rc 0x100 query error handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Let's not get bitten by an extension of the query struct and handle
the rc 0x100 error properly which does indicate that the UV has more
data for us.
