   9 When functions are inlined, it can make the system much more difficult
  10 to instrument using tools such as ftrace, BPF, crash, etc. Thus, to aid
  11 development and increase the system's observability, when the
  12 "--enable-debuginfo" flag is specified, the "-fno-inline" compilation
  13 option will be used for both userspace and kernel modules.
