flags != 0 has known error path too, and it's absolutely the same.
Sorry, read this after writing my previous reply, so this is a short addendum.
I see lots of people agreed on a new type. If my argument about reusing existing definitions is not
enough, you can ignore it. Three people beat one definitely. :)
And yes, since we are talking about it, actually KVM_MSI_VALID_DEVID flag is not yet a part of
mainline, so it's not set in stone. Then, perhaps you could throw it away completely and invent
KVM_SIGNAL_EXT_MSI ioctl for sending MSIs with device ID. This would also be consistent IMO.
Kind regards,
