函数名称：trace_fn_hex

函数原型：static enum print_line_t trace_fn_hex(struct trace_iterator *iter, int flags, struct trace_event *event)

返回类型：enum print_line_t

参数：

类型参数名称
struct trace_iterator *iter
intflags
struct trace_event *event
872  s等于 The below is zeroed out in pipe_read
874  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)
876  SEQ_PUT_HEX_FIELD(s, ip)
877  SEQ_PUT_HEX_FIELD(s, parent_ip)
879  返回: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.
