  3.3.  Howto Install Just A Single Module ?

  Let us assume that you already did 'make modules' and 'make
  modules_install'.  And later you did 'make clean' to free up disk
  space. And now, you want to change a "C" file in one of the modules
  and want to rebuild just that module and copy the module file to
  /lib/modules. How do you do it?

  You can compile just a single module file (say like foo.o) and install
  it.  For this simply edit the Makefile and change the SUBDIRS to add
  only those directories you are interested.

  For an example, if I am interested in installing only fs/autofs
  module, then I do the following :

  ______________________________________________________________________
  cd /usr/src/linux
  cp Makefile Makefile.my
  vi Makefile.my
  # And comment out the line having 'SUBDIRS' and add the
  # directory you are interested, for example like fs/autofs as below :
          #SUBDIRS        =kernel drivers mm fs net ipc lib abi crypto
          SUBDIRS         =fs/autofs
  # Save the file Makefile.my and give -
  make -f Makefile.my modules
  # This will create module autofs.o

  # Now, copy the module object file to destination /lib/modules
  make -f Makefile.my modules_install
  # And this will do 'cp autofs.o /lib/modules/2.4.18-19.8.0/kernel/fs/autofs'
