[PATCH 01/12] domain_conf: move duplicate check functions to domain_validate.c

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

 



virDomainDefCheckDuplicateDiskInfo() and virDomainDefCheckDuplicateDriveAddresses()
are static functions used by virDomainDefValidateInternal(). Let's
move them to domain_validate.c to start clearing up the path to
move virDomainDefValidateInternal().

Change the functions name slightly to be more on par with their
new home.
