(gdb) info line *0xffffffff8102ec38 Line 567 of "arch/x86/kernel/cpu/perf_event_intel_ds.c" starts at address 0xffffffff8102ec38 <intel_pmu_drain_pebs_buffer+24> and ends at 0xffffffff8102ec40 <release_pebs_buffer>. Line 567 isn't that helpful, it's just the last line of intel_pmu_drain_pebs_buffer() but that's possibly because I have done a git pull since the time I built the kernel so the source tree doesn't match up.
