Update.
2003-07-20 Ulrich Drepper <drepper@redhat.com> * Makefile (libpthread-routines): Add pthread_attr_getaffinity and pthread_attr_setaffinity. * Versions [libpthread] (GLIBC_2.3.3): Likewise. * sysdeps/unix/sysv/linux/pthread_attr_getaffinity.c: New file. * sysdeps/unix/sysv/linux/pthread_attr_setaffinity.c: New file. * pthread_attr_destroy.c: Free cpuset element if allocated. * pthread_create.c: Pass iattr as additional parameter to create_thread. * sysdeps/pthread/createthread.c: If attribute is provided and a new thread is created with affinity set or scheduling parameters, start thread with CLONE_STOPPED. * sysdeps/pthread/pthread.h: Declare pthread_attr_getaffinity and pthread_attr_setaffinity. * sysdeps/unix/sysv/linux/internaltypes.h (struct pthread_attr): Add cpuset element.
