Yonghong Song says:

====================
The patch set implements bpf syscall command BPF_MAP_GET_NEXT_KEY
for stacktrace map. Patch #1 is the core implementation
and Patch #2 implements a bpf test at tools/testing/selftests/bpf
directory. Please see individual patch comments for details.

Changelog:
  v1 -> v2:
   - For invalid key (key pointer is non-NULL), sets next_key to be the first valid key.
====================
