From 068ca522d5a563ac4ecc48c2c7c390102537fefd Mon Sep 17 00:00:00 2001 From: Daniel Xu Date: Wed, 23 Aug 2023 17:15:02 -0600 Subject: libbpf: Add bpf_object__unpin() For bpf_object__pin_programs() there is bpf_object__unpin_programs(). Likewise bpf_object__unpin_maps() for bpf_object__pin_maps(). But no bpf_object__unpin() for bpf_object__pin(). Adding the former adds symmetry to the API. It's also convenient for cleanup in application code. It's an API I would've used if it was available for a repro I was writing earlier.
