I don't think it's really necessary for this work to be suffering under some concern that pluggable storage will make it have to change. Sure, it might, but it also very well might not. For my 2c, anyway, this seems likely to get into the tree before pluggable storage does and it's pretty unlikely to be the only thing that that work will need to be prepared to address when it happens. > Work can happen in parallel, and I'm definitely not recommending that peo= ple > hold off on any patches that they want to provide feedback for, or submit > for a CommitFest. Yes, work can happen in parallel, and I don't really think there needs to be a concern about some other patch set when it comes to getting this patch committed. Thanks!
