Can we go back to posting diffs instead of hashes please ?

So while updating my list of bugs I've found this cycle, I noticed
I'd already posted this one a month ago on -rc2.
https://lkml.org/lkml/2013/5/21/327
which led us to this patch https://lkml.org/lkml/2013/5/24/379
After which I hit a bunch of what seem to be other RCU related bugs.

So maybe that patch was a winner after all and got dropped ?
