The symbol was moved using scripts/move-symbol-to-libc.py. The calls to __pthread_mutex_init, __pthread_mutexattr_init, __pthread_mutexattr_settype are now private and no longer need to be exported. This allows the removal of the newly added GLIBC_2.34 symbol versions for those functions. Also clean up some weak declarations in <libc-lockP.h> for these functions. They are not needed and potentially incorrect for static linking of mtx_init. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
