[Dirvish] [PATCH] v2: btrfs support

[Adrian von Bidder]

Heyho!

Now this is embarassing...  wrong assumptions and not enough testing 
resulted in dirvish-expire not working for btrfs trees. Sorry about that.

Fixed btrfs support attached.

As suggested, it would be sensible to rename the "btrfs" binary option into 
a "cow: btrfs" option, to allow future extension with support of other cow 
filesystems.  I don't have time for this right now though.

(And if anybody else is playing with btrfs: don't call btrfs defrag.  It 
currently expands cow files into separate copies, so your diskspace will 
probably explode. btrfs balance is fine.)

cheers
