I didn't think of ftrace_printk yet.
That's a good idea, this way we will see where the ftrace_printk was
called, in which
function at which depth....

Don't you think that would be better to have it as C comments.
We are in a C-style output and ftrace_printk are especially designed for
comments in a trace.
That would make sense to read:

       do_sync_read() {
          /* sock: 0x12345 flag: 1 */
          sock_aio_read() {
0.123 }
