So, if Btrfs starts zeroing at 1k, will that be acceptable for you?
Sure.

So, here's v0.12.
Any page size larger than 4K will not work with btrfs. All of the
extent stuff assumes that PAGE_SIZE = sectorsize.
I confirmed this by forcing mkfs.btrfs to use an 8K sectorsize on
sparc64 and I was
in the history?
It also totally screws the commit statistics, wiping me and John and the
committers we have preserved out, replacing everybody's committer with
David Miller.
I am well aware of this downside, sorry.

Something could be done:
we could enable drivers to have DMA-pools they manage that get mapped
and are re-used.
I would rather the DMA-pools be tied to PID's that way any bad behavior

Rebasing is low impact only if you don't have git downstream people.
Otherwise, you're just treating it as a useful quilt clone, really.

You don't see the problems as much, because you merge probably only
about a tenth of the volume I merge, and you can keep track of the

The fact is, that outlying code is where we have all the bulk of the

Something looks wrong here. Why would btrfs need to zero at all?
So that existing superblocks on the partition won't
be interpreted as correct by other filesystems. It's
a safety measure many mkfs programs use.
