[PATCH] qemuOpenFileAs: Lose bypassSecurityDriver

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

 



This argument is not used anymore. The only function that is
passing non-NULL (qemuDomainSaveMemory) does not actually care
for the value (after 23087cfdb) and every other caller just
passes NULL anyway.
