uretprobe(2) is an performance enhancement system call added to improve
uretprobes on x86_64.

Confinement environments such as Docker are not aware of this new system
call and kill confined processes when uretprobes are attached to them.

Since uretprobe is a "kernel implementation detail" system call which is
not used by userspace application code directly, pass this system call
through seccomp without forcing existing userspace confinement environments
to be changed.

[...]

With the changes I mentioned in each patch, I've applied this to
for-next/seccomp, with the intention of getting them into v6.14-rc2.

Thanks!
