[PATCH v6 13/14] KVM: selftests: Add memslot_flags parameter to memstress_create_vm()

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

 



Memslot flags aren't currently exposed to the tests, and are just always
set to 0. Add a parameter to allow tests to manually set those flags.
