Commit Message
This was added on Linux 5.6 (8649c322f75c96e7ced2fec201e123b2b073bf09)
as a way to retrieve a file descriptors for another process though
pidfd (created either with CLONE_PIDFD or pidfd_getfd). The
functionality is similar to recvmmsg SCM_RIGHTS.

The only ABI parts are: the function name, integer values for the pidfd and
targetfd, unsigned int flags, and flags has no constants today (reserved).
OK modulo the same NEWS issue discussed in patch 1.
