Doesn't this break the build at this point in the patch series?
Normally you add the code for the syscall first, and then you wire i

Emm.. "set_memory_region_io" doesn't represent the real testing purpose,
but not sure if things like "memory_region_page_refcount_test" become
better...

This commit marks kfuncs as such inside the .BTF_ids section. The upshot
of these annotations is that we'll be able to automatically generate
kfunc prototypes for downstream users. The process is as follows:
1. In source, use BTF_KFUNCS_START/END macro pair to mark kfuncs
2. During build, pahole i
=== Description ===
This is a bpf-treewide change that annotates all kfuncs as such inside
.BTF_ids. This annotation eventually allows us to automatically generate
kfunc prototypes from bpftool.
We store this metadata inside a yet-unused flags field inside struct
btf_id_set8 (thanks Kumar!). paho

Update testptp.c to exercise the new ptp method gettimex64any().
When only -x option is given the PTP_SYS_OFFSET_EXTENDED or
gettimex64() method is exercised while presence of -x with -y
will exercise PTP_SYS_OFFSET_ANY or gettimex64any() method.
-y option is to choose the timebase from available

The new mseal() is an syscall on 64 bit CPU, and with
following signature:
int mseal(void addr, size_t len, unsigned long flags)
addr/len: memory range.
flags: reserved.
mseal() blocks following operations for the given memory range.

The expression "source ../lib.sh" added to net/forwarding/lib.sh in commit
25ae948b4478 ("selftests/net: add lib.sh") does not work for tests outside
net/forwarding which source net/forwarding/lib.sh (1). It also does not
work in some cases where only a subset of tests are exported (2).
