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.

Recent versions of the Linux kernels and GNU libc contain support for
the System V/Unix98 naming scheme for PTYs, which assigns a common
device {\file /dev/ptmx\/} to all the masters (opening it will
automatically give you a previously unassigned PTY) and a subdirectory
{\file /dev/pts\/} for the slaves; the slaves are named with decimal
integers ({\file /dev/pts/$\#$\/} in our notation). This removes the
problem of exhausting the namespace and enables the kernel to
automatically create the device nodes for the slaves on demand using
the {\file devpts\/} filesystem.

The entire namespace /dev/[pt]ty[p-za-o][0-9a-z] should be considered
reserved for the future use of PTYs. Should more than 936 PTYs ever
become a necessity, we will likely adopt a System V-like scheme by
which PTYs use a subdirectory of /dev.
Recent versions of the Linux kernels and GNU libc contain support for
the System V/Unix98 naming scheme for PTYs, which assigns a common
device, /dev/ptmx, to all the masters (opening it will automatically
give you a previously unassigned PTY) and a subdirectory, /dev/pts,
for the slaves; the slaves are named with decimal integers (/dev/pts/#
in our notation). This removes the problem of exhausting the
namespace and enables the kernel to automatically create the device
nodes for the slaves on demand using the "devpts" filesystem.
