Linux-2.1.115 - code freeze.

Ok, we've been in a tentative code freeze for a long time, and now it's
final. I've made a 2.1.115 that I hope is good enough, and I won't be
accepting anything but bug-fixes until 2.2..
There are two long-standing patches that I'm still considering:

 - devfs
 - dynamic fd's

and I kind of expect that they'll go in (devfs is configurable, so if you
don't want it you don't need to care, and the dynamic fd's save some
memory and speed certain things up a bit). The reason they're not in now
is mainly that I've been trying to get everything else off my plate, and I
want to ruminate on them in peace for a while.
Bug-fixes are still (and will always be) accepted,

                Linus

+Unix98 PTY support
+CONFIG_UNIX98_PTYS
+  Linux traditionally uses BSD-like /dev/ptyxx and /dev/ttyxx names
+  for pseudo-ttys (PTYs).  This scheme has a number or problems.  The
+  GNU C library 2.1 and later, however, supports the Unix98 naming
+  standard, using a cloning device /dev/ptmx and numbered devices in a
+  subdirectory /dev/pts/xxx.  The device nodes in /dev/pts can be
+  automatically generated by the devpts virtual filesystem.
+
+  Say Y here if you are uncertain, unless you are very short on memory.

+Maximum number of Unix98 PTYs in use (0-2048)
+CONFIG_UNIX98_PTY_COUNT
+  The maximum number of Unix98 PTYs that can be used at any one time.
+  The default is 256, and should be enough for desktop systems,
+  however, server machines which support incoming telnet/rlogin/ssh
+  connections may want to increase this.  When not in use, each
+  additional set of 256 PTYs occupy approximately 8K of kernel memory
+  on 32-bit architectures.
