Subject: Define _GNU_SOURCE for all implementation files rather than getcpu.h
X-Git-Tag: v1.9.8~9
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;h=5ad63a1632792c8bc40fa5bc9f7f45f037a68032;p=lttng-ust.git

Define _GNU_SOURCE for all implementation files rather than getcpu.h

If implementation files include the sched.h header prior to having
_GNU_SOURCE defined by getcpu.h, we get in a situation where
sched_getcpu() can be undeclared.
