Subject: [PATCH v2 bpf-next 0/4] introduce bpf_iter for task_vma

This set introduces bpf_iter for task_vma, which can be used to generate
information similar to /proc/pid/maps or /proc/pid/smaps. Patch 4/4 adds
an example that mimics /proc/pid/maps.

Changes v1 => v2:
  1. Small fixes in task_iter.c and the selftests. (Yonghong)

Song Liu (4):
  bpf: introduce task_vma bpf_iter
  bpf: allow bpf_d_path in sleepable bpf_iter program
  libbpf: introduce section "iter.s/" for sleepable bpf_iter program
  selftests/bpf: add test for bpf_iter_task_vma
