Howard Cochran b30f75eba2 tools lib traceevent: Handle __print_hex(__get_dynamic_array(fieldname), len) ... The kernel has a few events with a format similar to this excerpt: field:unsigned int len; offset:12; size:4; signed:0; field:__data_loc unsigned char[] data_array; offset:16; size:4; signed:0; print fmt: "%s", __print_hex(__get_dynamic_array(data_array), REC->len) trace-cmd could already parse that arg correctly, but print_str_arg() was unable to handle the first parameter being a dynamic array. (It just printed a "field not found" warning). Teach print_str_arg's PRINT_HEX case to handle the nested PRINT_DYNAMIC_ARRAY correctly. The output now matches the kernel's own formatting for this case.
