In Linus' tree: tools/lib/traceevent/Documentation/libtraceevent-func_apis.txt:or events have "%pF" or "%pS" parameter in its format string. It is common to tools/lib/traceevent/event-parse.c: if (asprintf(&format, "%%pf: (NO FORMAT FOUND at %llx)\n", addr) < 0) tools/lib/traceevent/event-parse.c: if (asprintf(&format, "%s: %s", "%pf", printk->printk) < 0) And these in -next: drivers/scsi/lpfc/lpfc_hbadisc.c: "3185 FIND node filter %pf DID " drivers/scsi/lpfc/lpfc_hbadisc.c: "3186 FIND node filter %pf NOT FOUND.\n", filter); drivers/scsi/lpfc/lpfc_sli.c: "(%d):0307 Mailbox cmd x%x (x%x/x%x) Cmpl %pf "
