According to man copy_file_range [1] EINTR also may happen "for files on some
NFS mounts.", so it is not new problem, it is documented behavior.
You may ask authors, see here: https://reviews.freebsd.org/D20584

Since it is documented, it should be handled, like it handled for
send()/recv()/write()/read()/connect()/kevent()/epoll_wait()/nanosleep()... in
multiple well designed apps.

Documented error handling is not workaround.

You may continue research and probably as result you will find out that it work
as it should.

11 month is gone, I do not want back to this investigation.


Probably also patch required for:
bin/cat/cat.c
usr.bin/xinstall/xinstall.c
and multiple staff in tests.
