vmlinux.h declarations are more ergnomic, especially when working with
kfuncs. The uapi headers are often incomplete for kfunc definitions.
This commit also switches bitfield accesses to use CO-RE helpers.
Switching to vmlinux.h definitions makes the verifier very
unhappy with raw bitfield accesse
test_progs is better than a shell script b/c C is a bit easier to

DAMON provides almost all control to the user via its sysfs interface.
For that, the interface provides plenty of files and hierarchies. The

As Guillaume pointed, many selftests create namespaces with very common
names (like "client" or "server") or even (partially) run directly in init_net.
This makes these tests prone to failure if another namespace with the same
name already exists. It also makes it impossible to run several instance
Add a lib.sh for net selftests. This file can be used to define commonly
used variables and functions. Some commonly used functions can be moved
from forwarding/lib.sh to this lib file. e.g. busywait().
Add function setup_ns() for user to create unique namespaces with given
prefix name.
