[tor-commits] [tor/master] trace: Move LTTng specific declartion to .inc file
commit d80c34d214f88c0831ce7cf7595c5e6e8b6fa168
Author: David Goulet <dgoulet@xxxxxxxxxxxxxx>
Date: Thu Feb 13 13:25:42 2020 -0500
trace: Move LTTng specific declartion to .inc file
LTTng tracepoint probe declaration is not really following a C standard that
coccinelle and checkSpace.pl likes.
Move everything to a .inc file and standardize the trace_probes_circuit.h
header to include that LTTng specific file if the instrumentation was enabled
at configure time.
Part of #32910
