* sysdeps/unix/sysv/linux/kernel-features.h: Define
__ASSUME_TMPFS_NAME. * sysdeps/unix/sysv/linux/shm_open.c [!__ASSUME_TMPFS_NAME] (where_is_shmfs): Don't test for obsolete shm filesystem name. * sysdeps/unix/sysv/linux/getsysstats.c: Don't search for proc mount point. We assume procfs is mounted at /proc in many other places already.
