Demonstrations of syncsnoop, the Linux bpftrace/eBPF version.


Tracing file system sync events:

# ./syncsnoop.bt
Attaching 7 probes...
Tracing sync syscalls... Hit Ctrl-C to end.
TIME      PID    COMM             EVENT
02:02:17  27933  sync             tracepoint:syscalls:sys_enter_sync
02:03:43  27936  sync             tracepoint:syscalls:sys_enter_sync

The output shows calls to the sync() syscall (traced via its tracepoint),
along with various details.
