I took a shot based on 3.9.11 + e6c495a96ce0. The reason why I don't simply use the current git master is, that for some reasons my linux-image-*.deb become 750MB and larger since 3.10.y and I have no clue at all why and what to do about it. The patch failed. Due to my outstanding incompetence I resorted into applying it onto master, cherry-picking that back and trying to resolve the remaining conflicts correctly. > - I have no idea whether this will fix the problem Ben sees, but I > feel happier about the code, because now any place that forgets to set > up start/end will work just fine, because they are always valid.

I git-fsck'ed successfully around 30 times in a row. And even all the other things still seem to work ;-) Honestly I have to confess that I'm deeply impressed how this finally worked out: I just threw a particular, innocent-looking commit hash and nothing more into the round. And while still being unsure if this might be a plain user space issue, only 24h later I received a 11kb sized kernel patch (with blatant typos in it !1! *g* ) apparently solving my issue. /me happy now, too! :) - Ben -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
