Subject: Re: [PATCH v2 00/22] add Object Storage Media Pool (mpool)

I don't think this belongs into the kernel.  It is a classic case for
infrastructure that should be built in userspace.  If anything is
missing to implement it in userspace with equivalent performance we
need to improve out interfaces, although io_uring should cover pretty
much everything you need.
