Linux STREAMS (LiS)

You can remove LiS from your system by following this procedure.

In your LiS installation directory do a "make very-clean". This will remove any character special files in /dev that were created by an earlier "make install" plus any patches that were placed into the kernel source tree. It will also remove STREAMS utilities that were installed in /usr/sbin and /usr/local/bin. Note: for kernel version 2.0.36 and later there will be no patches in the kernel source tree unless you requested direct linking of LiS with the kernel at LiS installation time.

Then, in the directory above, enter "rm -r LiS-2.12". Substitute whatever the version of LiS is that you are removing. Then do "rm /usr/src/LiS" to remove the symbolic link to the LiS installation directory.

If you were linking LiS directly into the kernel, you need to rebuild your kernel.

Problems Removing LiS (obsolete)

If the automatic removal if LiS does not seem to go well you can delete the STREAMS oriented patches from your kernel source by hand just by editing a few files.

In your kernel source directory, edit the file init/main.c. Scan for lines containing the word "STREAMS". Delete all such line and save the file.

Now edit the file drivers/char/Makefile. Scan for lines containing the word "STREAMS". Before deleting all such lines, examine the first such line in context to see if it looks like the following:

L_OBJS   := tty_io.o n_tty.o tty_ioctl.o mem.o random.o \

          /usr/src/LiS-1.25/streams.o           # STREAMS

If so then delete the backslash from the first line as well as the line containing the word "STREAMS". Then delete all other lines in this file containing the word "STREAMS".

Alternate Method (obsolete)

If LiS is the only patch that you have applied to the files init/main.c and drivers/char/Makefile then you can do the following.

Change to the directory ./init in your kernel source tree and do the following.

mv main.c main.c.streams

mv main.c.orig main.c

Then change to the directory drivers/char (cd ../drivers/char) and do the following.

mv Makefile Makefile.streams

mv Makefile.orig Makefile
