SubjectRe: [RFC] sane access to per-fs metadata (was Re: [PATCH] Documentation/ioctl-number.txt)

But ioctl requires allocation of numbers. Ugly and hard to scale.

Alex Viro's idea is cleaner, but still requires a fair amount of
coding even for simple interfaces.

Why not have a kernel thread and use standard RPC techniques like
sockets? Then you'd not have to invent anything unimportant like
Yet Another IPC Technique.
