@kawasaki
block: Introduce the UFQ I/O scheduler
655d77d 
Introduce IOSCHED_UFQ, a blk-mq elevator ("ufq: User-programmable
Flexible Queueing") whose policy is supplied by an eBPF program via
struct_ops (insert, dispatch, merge, finish, etc.).

When no eBPF program is attached, the UFQ I/O scheduler uses a simple,
per-ctx queueing policy (similar to none). After an eBPF program is
attached, the user-defined scheduling policy replaces UFQ’s built-in
queueing policy, while per-ctx queues remain available as a fallback
mechanism.

tools/ufq_iosched: add BPF example scheduler and build scaffolding
fdc958e 
Add ufq_iosched as a simple example for the UFQ block I/O scheduler,
In the ufq_simple example, we implement the eBPF struct_ops hooks the
kernel exposes so we can exercise and validate the behavior and stability
of the kernel UFQ scheduling framework. The Makefile and directory
layout are modeled after sched_ext.

This mirrors the sched_ext examples pattern so developers can experiment
with user-defined queueing policies on top of IOSCHED_UFQ.
