Re: [libvirt] [PATCH v1 03/23] virSecurityDACSetOwnershipInternal: Don't chown so often

It's better if we stat() file that we are about to chown() at first and check if there's something we need to change. Not that it would make much difference, but for the upcoming patches we need to be doing stat() anyway.
