Using linux-3.18.y branch, perf build fails with the following:
$ make -s -j16 -C tools/perf V=1 WERROR=0 NO_LIBUNWIND=1
HAVE_CPLUS_DEMANGLE=1 NO_GTK2=1 NO_LIBNUMA=1 NO_STRLCPY=1 NO_BIONIC=1
prefix=/usr DESTDIR=/tmp/builddir/build all
[...]
util/session.c: In function ‘__perf_session__process_pipe_events’:
util/session.c:1093:36: error: ‘oe’ undeclared (first use in this function)
ordered_events__set_copy_on_queue(oe, true);
^
util/session.c:1093:36: note: each undeclared identifier is reported only
once for each function it appears in
This patch fixes it for linux-3.18.y branch.
Fixes: 95b33b99cdd6 ("perf inject: Copy events when reordering events in pipe
mode")
