Opening them any\n: other way is not allowed. Vegard Nossum found that previously this was not\n: the case and mknod foo c 128 42; cat foo would produce nasty diagnostics\n:\n: Signed-off-by: Alan Cox \u003calan@redhat.com\u003e\n: Signed-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n\ndevpts_get_tty() returns non-null only for inodes on devpts, but there is no\ninodes for master-devices, /dev/ptmx (/dev/pts/ptmx) is the only way to open them.\nThus we can completely forbid lookup for master-devices and eliminate that hack in\ntty_init_dev() because tty_open() will get EIO from tty_driver_lookup_tty().\n\nSigned-off-by: Konstantin Khlebnikov \u003ckhlebnikov@openvz.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n",
