About three weks ago :( Sorry. I am just frustrated by kernel development process. Bugs are untracked and get lost. Patches are untracked and get lost. State of patches is nontransparent for most people, including author (sic!). I've just got a reply on another patch along the lines of "oh, I've already merged some unspecified version of this patch, so please resent all changes since that unspecified version in a separate patch" (what?). It's unclear what is the designated tree and who is the designated responsible merger. Merging a build fixing patch takes months (!) whereas most other modern project processes today are capable of merging such changes into (the single head) tree within an hour provided only a single maintainer from a group is around, and they simply need to click a button because all tests, style and mergability checks have already run by that time. Resending patches thing should not exist unless the patch needs to be updated, condition which is detectable automatically. Andrew, none of this is related to you personally. That's the process we have today, and I understand you are doing your best.
