Subject: [PATCH] Make "-fno-inline" compile option more accessible

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