[Devel] [PATCH RFC] fsio: filesystem io accounting cgroup

[Theodore Ts'o]

Another major problem with this concept is that it lumps all I/O's
into a single cgroup.  So I/O's from pseudo filesystems (such as
reading from /sys/kernel/debug/tracing/trace_pipe), networked file
systems such as NFS, and I/O to various different block devices all
get counted in a single per-cgroup limit.

This doesn't seem terribly useful to me.  Network resources and block
resources are quite different, and counting pseudo file systems and
ram disks makes no sense at all.
