module state:permanent

["amit mehta" <amit4g@xxxxxxxxx>]

Hi All,

Why would some module's state become permanent ?
i inserted one module and when i try to remove it, i get:
ERROR: Removing 'procsfs1': Device or resource busy

<lsmod snip>

Module                  Size  Used by
procsfs1                3204  0 [permanent] <---------

<lsmod snip>

The program code is here:
http://tldp.org/LDP/lkmpg/2.6/html/x710.html

rmmod help shows:
root@venus:/home/amit/# rmmod --h
Usage: rmmod [-fhswvV] modulename ...
 -f (or --force) forces a module unload, and may crash your
    machine.  This requires the Forced Module Removal option
    when the kernel was compiled.

i looked into the .config file under /usr/src/linux
and this seem to be the reason for even the --force option in rmmod not working:
# CONFIG_MODULE_FORCE_UNLOAD is not set
