Mocking of the __open_2 function was added in commit 459f071cacf30af9df93b7d090b1bda71b0ef20f Author: Michal Privoznik <mprivozn@redhat.com> Date: Thu Aug 15 16:37:17 2019 +0200 virpcimock: Mock __open_2() This function only exists in glibc, however, and the mocking code runs on systems not using glibc, such as FreeBSD. Even Linux hosts might be using a different libc impl, though we don't actively try to support that. Signed-off-by: Daniel P.
