Hi, Kent Overstreet.  Thanks for Cc'ing me and for the promising work.

Were you able to do sanity tests with aoe this time around?  Last time, basic I/O was not working with the immutable biovec patches applied.

Here is my 28 June email about my experiences with git://evilpiepirate.org/~kent/linux-bcache.git at that time.  It also includes information about creating an easy software-only aoe test environment.
