A comment is sufficient. Here's a similar comment I'm adding in my
series for virDomainBlockCopy:
/* bandwidth in bytes/s. Caller must lock vm beforehand, and not

static int
qemuDomainBlockCopyCommon(virDomainObjPtr vm,
virConnectPtr conn,
const char *path,
virStorageSourcePtr dest,
unsigned long long bandwidth,
unsigned int flags)
