   4 Subject: [PATCH] src/Kbuild: change missing CONFIG_TRACEPOINTS to warning
   5
   6 Taken from a previous patch to the main lttng-modules Makefile, by
   7 Otavio Salvador:
   8
   9   The lttng-modules are being pulled by the tools-profile image feature,
  10   however, not every kernel has the CONFIG_TRACEPOINTS feature enabled.
  11
  12   This change makes the build do not fail when CONFIG_TRACEPOINTS is not
  13   available, allowing it to be kept being pulled by default.
  14
  15 Upstream-Status: Inappropriate [embedded specific]
