From 6384cf4132a39dd0ada7991d551554b718041da9 Mon Sep 17 00:00:00 2001 From: Prakash Surya Date: Fri, 15 Sep 2017 11:47:11 -0700 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.
