Subject: Fix build and load against linux-2.6.33.x
X-Git-Tag: v2.0.7~1
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=d25a4cef8348ff361e9e4ca30d451159fe59d1e8;p=lttng-modules.git

Fix build and load against linux-2.6.33.x

* lttng-event.h declared but did not implement
  lttng_add_perf_counter_to_ctx on kernel >=2.6.33, the implementation
  was in lttng-context-perf-counters.c, which was only included for
  kernel >=2.6.34.  This prevented the module from being loaded.

* on kernel 2.6.33.x, lttng-context-perf-counters.c complains about
  implicit declaration for {get,put}_online_cpus and
  {,un}register_cpu_notifier; so fix header inclusion.
