    Oh, and since I didn't react initially, let me react now that Andrei
    found a bug here: why was this patch auto-selected for 5.5 stable in
    the first place?

    It wasn't really a fix, and there's no Fixes: tag or stable tag in
    there. Yeah, there's a reference to an old commit, but that one isn't
    even a kernel commit.

    Yeah, the performance improvements are quite nice if you hit the case
    this matters for, but still..

    Linus
