TTY, devpts: document pty count limiting
Logic has been changed in kernel 3.4 by commit e9aba5158a80 ("tty: rework pty count limiting") but still not documented. Sysctl kernel.pty.max works as global limit, kernel.pty.reserve ptys are reserved for initial devpts instance (mounted without "newinstance"). Per-instance limit also could be set by mount option "max=%d". Signed-off-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
