One object may be\nassociated with multiple paths because an object can be pinned multiple times\n\nPatch3 adds command line option to enable this functionality. Making it optional\nbecause scanning bpf-fs can be costly.\n\nv1->v2:\n - Dynamically identify bpf-fs moutpoint\n - Close files descriptors before returning on error\n - Change command line option from {-l|--pinned} to {-f|--bpffs}\n - Updated documentation\n - Fixed line break for proper output formatting\n - Code style: wrapped lines > 80, used reverse christmastree style\n\nPrashant Bhole (3):\n tools: bpftool: open pinned object without type check\n tools: bpftool: show filenames of pinned objects\n tools: bpftool: optionally show filenames of pinned objects\n\n tools/bpf/bpftool/Documentation/bpftool-map.rst | 5 +-\n tools/bpf/bpftool/Documentation/bpftool-prog.rst | 5 +-\n tools/bpf/bpftool/common.c | 108 ++++++++++++++++++++++-\n tools/bpf/bpftool/main.c | 18 +++-\n tools/bpf/bpftool/main.h | 21 ++++-\n tools/bpf/bpftool/map.c | 22 +++++\n tools/bpf/bpftool/prog.c | 25 ++++++\n 7 files changed, 198 insertions(+), 6 deletions(-)"}
