Subject[PATCH -tip v3 05/11] perf-probe: Show in what binaries/modules probes are set
From
Date
Show the name of binary file or modules in which the probes
are set with --list option.

Without this change;

# ./perf probe -m drm drm_av_sync_delay
# ./perf probe -x perf dso__load_vmlinux

# ./perf probe -l
probe:drm_av_sync_delay (on drm_av_sync_delay)
probe_perf:dso__load_vmlinux (on 0x000000000006d110)

With this change;

# ./perf probe -l
probe:drm_av_sync_delay (on drm_av_sync_delay in drm)
probe_perf:dso__load_vmlinux (on 0x000000000006d110 in /kbuild/ksrc/linux-3/tools/perf/perf)
