I've thought about ditching resierfs since Hans' "legal issues". But
v3 of resierfs just runs so well that it's hard to give it up. Having
said that, I am planning on looking at ext4. And jfs is rock solid as
a journaling file system too, which is probably what Dotan wants to
know if he's thinking about moving away from ext3.
