Solution: VOB on solaris can't be mounted on linux

According to clearcase webdpage, aotofs can't mount /net/"hostname"/, the way solaris like. autofs4 can overcome this problem.

Try to install aotofs4 module. I fail to compile the autofs4 module, so study some background acknowledge. 

some LKM tools: lsmod, modinfo, modprobe

All LKM source code include "linux/module.h" or #define MODULE

modprobe's argument "module name" is not necessarily a real  module name. It can be symbollic name in /etc/modules.conf

About Modversioning: I turn off CONFIG_MODVERSIONS when confg kernel, then I can compile autofs4, no error in module.h repeat. I am  confuse....
