[PATCH 02/11] perf trace: Add getrandom beautifier related defines for older systems

From: Arnaldo Carvalho de Melo
Date: Thu Apr 14 2016 - 08:36:27 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Were the detached tarball (make perf-tar-src-pkg) build was failing because
those definitions aren't available in the system headers.

On RHEL7, for instance:

builtin-trace.c: In function âsyscall_arg__scnprintf_getrandom_flagsâ:
builtin-trace.c:1113:14: error: âGRND_RANDOMâ undeclared (first use in this function)
P_FLAG(RANDOM);
^
builtin-trace.c:1114:14: error: âGRND_NONBLOCKâ undeclared (first use in this function)
P_FLAG(NONBLOCK);
^
