It's called a post, the same as you used for Hacker News.

And yes, I debugged one of the issues. I made the second comment in one of them. Markus Mayer did some debugging, too.

Then I had to deal with something completely unrelated to computers for the rest of that day and several days thereafter, and came back to this.

The problem with compiling code that used new kernel features was a bit poorly done. Anyone with any experience knows that a simple #if defined(__linux__) , which is a platform test, does not cut it for feature testing. M. Mayer went with an autotools test, which is what I'd have done too.

The problem with the on-the-wire protocol is a tricky one, and caused by suddenly being conservative in what rsync accepts apparently without much testing of what out-of-range stuff in-the-wild rsync sends.
