-        bool "Preemptible Kernel"
-        help
-          This option reduces the latency of the kernel when reacting to
-          real-time or interactive events by allowing a low priority process to
-          be preempted even if it is in kernel mode executing a system call.
-          This allows applications to run more reliably even when the system is
-          under load.

-        ---help---
-          A pseudo terminal (PTY) is a software device consisting of two
-          halves: a master and a slave. The slave device behaves identical to
-          a physical terminal; the master device is used by a process to
-          read data from and write data to the slave, thereby emulating a
-          terminal. Typical programs for the master side are telnet servers
-          and xterms.
-
-          Linux has traditionally used the BSD-like names /dev/ptyxx for
-          masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
-          has a number of problems. The GNU C library glibc 2.1 and later,
-          however, supports the Unix98 naming standard: in order to acquire a
-          pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
-          terminal is then made available to the process and the pseudo
-          terminal slave can be accessed as /dev/pts/<number>. What was
-          traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
-          The entries in /dev/pts/ are created on the fly by a virtual
-          file system; therefore, if you say Y here you should say Y to
-          "/dev/pts file system for Unix98 PTYs" as well.
-
-          If you want to say Y here, you need to have the C library glibc 2.1
-          or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
-          Read the instructions in <file:Documentation/Changes> pertaining to
-          pseudo terminals. It's safe to say N.

-          machines which support incoming telnet/rlogin/ssh connections and/or
-          serve several X terminals may want to increase this: every incoming
-          connection and every xterm uses up one PTY.
-
