Christophe,
the test io interval has been recently removed from dm in favour of
user space path revalidation (of course that needs precautions, eg mlockall())
in the application.
Thanks for noting. I will update the doc, but I need a bit more info :
Have you a prototype at hand ? Do you expect storage HW vendor will
provide their own path revalidation primitives ? ... Have you message
you want to pass to the HW vendors in this doc ?
Are you aiming at replacing the partitioning code in Linux altogether by running
kpartx in the early boot environment, setting up respective mapped devices ?
M Viro told me nearly 2 years back that it was doable but a little
early. In the interim, the two partitioning scheme can co-exist : keep
in-kernel partitions for legacy disks, but use DM/kpartx for any new
type of disk that would otherwise require kernel code to handle parts :
md, loop, ataraid, ...
