 Hi Chris,

 since rc-6 seems to be the last rc for 3.0 and in case you're already
 preparing your pull request for 3.1, can you please pull the following
 updates for scrub, based on your for-linus tree (2f7e33d432)?

 git://git.kernel.org/pub/scm/linux/kernel/git/arne/btrfs-unstable-arne.git
 for-chris

 It just contains the readahead patch, which gives a significant
 performance improvement for scrub. Currently scrub is the only
 consumer.

 Thanks,
 Arne

Oh, I completely forgot about that. You're right of course. I pushed
the for-chris branch again, it now looks like this:

[GIT PULL] scrub updates for 3.1

I'd like to avoid the ioctl for now, since once it is there we're stuck
with it forever.  At least for the 3.1 pull lets keep it out please.
