From 23ce1cf35a59a4fdb3dabe073e3d1fe2b76fb0ca Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 17 May 2021 09:59:14 +0200 Subject: nptl: Move __nptl_create_event, __nptl_death_event into libc In libthread_db, use the exported GLIBC_PRIVATE symbols directly instead of relying on _thread_db_* variables in libpthread (which used to be created by the DB_FUNCTION macros).
