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.
