Thanks.
I agree that it is unfortunate that struct filename increases, but it seemed liked a valid tradeoff considering that we got to remove the getname()/putname() hacks in favor of a more traditional approach. As far the int versus bitfield, I suppose I favor the int in this particular case, but if the fs folks want a bitfield I can do that. > Reviewed-by: Richard Guy Briggs <[email protected]> Thanks for taking the time to review the patchset. -- paul moore security @ redhat -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
