Then I strongly prefer squashing. (Greg also mentions this > in one of his seminars.) Sure, I totally agree. I strongly dislike when people introduce breakage and then fix it later in the same series. It's pretty obvious to me, each incremental step needs to work by itself - if it doesn't then it should be reworked before it gets merged. I personally prefer to separate features from fixes. Fixes are always folded into the original patch. > What really makes me mad is the the above pattern + claim that > it must be done in that way to preserve authorship.

I suppose I prefer to stop for coffee in every village then. =) / magnus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
