From ffa0c1cf59596fba54546ea828305acfcc2cf55e Mon Sep 17 00:00:00 2001 From: Yonghong Song Date: Sat, 15 Dec 2018 22:13:52 -0800 Subject: bpf: enable cgroup local storage map pretty print with kind_flag Commit 970289fc0a83 ("bpf: add bpffs pretty print for cgroup local storage maps") added bpffs pretty print for cgroup local storage maps. The commit worked for struct without kind_flag set. This patch refactored and made pretty print also work with kind_flag set for the struct.
