Merge branch 'libbpf: support non-mmap()'able data sections'
Andrii Nakryiko says:
====================
Make libbpf more conservative in using BPF_F_MMAPABLE flag with internal BPF
array maps that are backing global data sections. See patch #2 for full
description and justification.
Changes in this dataset support having bpf_spinlock, kptr, rb_tree nodes and
other "special" variables as global variables. Combining this with libbpf's
existing support for multiple custom .data.* sections allows BPF programs to
utilize multiple spinlock/rbtree_node/kptr variables in a pretty natural way
by just putting all such variables into separate data sections (and thus ARRAY
maps).
v1->v2:
- address Stanislav's feedback, adds acks.
