I think this needs more discussion. Boris, Brian, will you be at Embedded Linux Conference Europe in Dublin? Maybe we can discuss these issues (data retention, ff-checks, etc...) in person and figure out where to address them. I really want to avoid ad-hoc solutions. :) > Thanks. > In your opinion, enabling chk_io is correct to rough estimate the overhead or > does it enable too much checks?
