To help understand the failure. [acme@zoo linux]$ perf test -v 30 30: Test thread mg sharing : --- start --- test child forked, pid 12275 FAILED tests/thread-mg-share.c:68 wrong refcnt (4 != 3) test child finished with -1 ---- end ---- Test thread mg sharing: FAILED! [acme@zoo linux]$ This is under investigation, the thread__delete() calls were replaced with thread__put(), and those cause mismatches because now we need to be more judicious with the thread lifetime management. I.e. previously the thread__delete() would drop the map_group refcount, but now since thread__put doesn't call thread__delete() necessarily. because we have other refcount holders, the map_group refcount will not be as we expected when this test was implemented. Will be fixed soon...
