It's all about block layer and nothing more. Am I right?
So, you want to link some completely unrelated subsystems like NFS into the
block layer?
Heh, yeah, sure, network QoS is completely unrelated to sockets too,
right?
And, no, blkio wouldn't have anything to do with NFS. Where did you
get that idea?
My concept it cgroup which would control io operation on vfs layer for all
filesystems.
It will account and manage IO operations. I've found really lightweight
technique
for accounting and throttling which don't introduce new locks or priority
inversions
(which is major problem in all existing throttlers, including cpu cgroup rate
limiter)
So, I've tried to keep code smaller, cleaner and saner as possible while you
guys are
trying to push me into the block layer =)
