Name:TRACE_FN

Proto:static enum print_line_t trace_fn_trace(struct trace_iterator *iter, int flags, struct trace_event *event)

Type:enum print_line_t

Parameter:

TypeParameterName
struct trace_iterator *iter
intflags
struct trace_event *event
838  s = The below is zeroed out in pipe_read
840  The trace_assign_type is a verifier that the entry type is* the same as the type being assigned. To add new types simply* add a line with the following format:* IF_ASSIGN(var, ent, type, id);* Where "type" is the trace type that includes the trace_entry(field, ent)
842  seq_print_ip_sym(s, ip, flags)
844  If flags & TRACE_ITER_PRINT_PARENT && parent_ip Then
845  trace_seq_puts(s, " <-")
846  seq_print_ip_sym(s, parent_ip, flags)
849  trace_seq_putc(s, '\n')
851  Return Several functions return TRACE_TYPE_PARTIAL_LINE if the trace_seq* overflowed, and TRACE_TYPE_HANDLED otherwise. This helper function* simplifies those functions and keeps them in sync.
