Hi Jonathan,
I'm
not sure about specific patches I'm afraid - the most common theme on
the btrfs mailing list seems to be 'try the latest version'.
With
this in mind, perhaps sync to the upcoming 3.6 kernel (not sure how easy
or otherwise this is), or perhaps align to what Oracle and Suse have
done for Enterprise Support:
https://btrfs.wiki.kernel.org/index.php/Getting_started#Enterprise_distributions_with_btrfs_support
However, I get a 'gut
feel' (so no stats to back this up) that the amount of interest in btrfs
will lead to a lot of instalations trying it, so shipping the most
mature version as is practical may be sensible as warnings around
backups etc are frequently ignored. The
3.2 version being shipped isn't a big issue for me personally as it's working fine just now, so happy to be guided by the Debian maintainers in terms of cost/benefit.
Also,
there was some mention of an upcoming update on btrfs-progs on the
btrfs mailing list too - another candidate to sync perhaps?
Thanks.
