Hi,
I'm interested in discussing how to pass protection information to and from
userspace. Maybe Martin could be enlisted for the discussion.
I read that some work has already been done in this area but have not been able
to locate it. It looks like the bio-integrity code already makes it possible
to generate the t10-dif crc in the filesystem. It would be good to be able to
get the guard and application tags back out to backup applications such as
xfsdump. Enabling other applications to generate their own tags in userspace
is also interesting.
Regards,
Ben
