NAME
       rmmod -- simple program to remove a module from the Linux Kernel

SYNOPSIS
       rmmod [-f]  [-w]	 [-s]  [-v]  [modulename]

DESCRIPTION
       rmmod  is  a  trivial program to remove a module from the kernel.  Most
       users will want to use modprobe(8) instead, with the -r option.


OPTIONS
       -v --verbose
		 Print messages about what  the	 program  is  doing.   Usually
		 rmmod only prints messages if something goes wrong.


       -f --force
		 This  option  can  be	extremely  dangerous: it has no effect
		 unless CONFIG_MODULE_FORCE_UNLOAD was set when the kernel was
		 compiled.  With this option, you can remove modules which are
		 being used, or which are not designed to be removed, or  have
		 been marked as unsafe (see lsmod(8)).


       -w --wait Normally,  rmmod  will	 refuse to unload modules which are in
		 use.  With this option, rmmod will isolate  the  module,  and
		 wait  until  the module is no longer used.  Noone new will be
		 able to use the module, but it's up to you to make  sure  the
		 current  users	 eventually finish with it.  See lsmod(8)) for
		 information on usage counts.


       -s --syslog
		 Send errors to the syslog, instead of standard error.


       -V --version
		 Show version of program, and exit.   See  below  for  caveats
		 when run on older kernels.


BACKWARDS COMPATIBILITY
       This version of rmmod is for kernels 2.5.48 and above.  If it detects a
       kernel with support for old-style modules (for which much of  the  work
       was  done in userspace), it will attempt to run rmmod.old in its place,
       so it is completely transparent to the user.
