I would say:

@flags: control queue descriptor flags

IMHO it makes more sense to call this "flags" instead of flag, since you
could pass arbitrary flags not just one flag.

Additionally, this patch did not apply cleanly to next-queue, due to
conflicts with other work on the tree.

Would you mind renaming this field and rebasing this series?
