is called with a dirfd to "/proc". Here too the fake file lookup
may not catch the special file because no dirfd is used to
determine if the path is in /proc.

Hi,
This is v3 of the openat2 support in linux-user. Thanks again for the
excellent second round of feedback from Richard Henderson.
This version tries to be closer to the kernels behavior, i.e. now
do_openat2() uses a new copy_struct_from_user() helper that is very
similar
atively to ignoring
we could simply fail with `-TARGET_ENOSYS` (or similar) if
