Module Names - Hyphen Converted to Underscore

Module Names - Hyphen Converted to Underscore

[AJM]

I have compiled stock (kernel.org) 2.6.3 and 2.6.9 kernels which exhibit 
the following unusual behaviour on module loading: If the kernel module 
has a hyphen in its name, then this appears to be translated into an 
underscore by the kernel, such that, for example after "insmod 3w-xxxx", 
lsmod shows "3w_xxxx", "rmmod 3w-xxxx" fails but "rmmod 3w_xxxx" succeeds.

The distribution I am compiling the kernels under is Mandrake 10.0, and 
if I compile the 2.6.3-4mdk kernel source supplied with the distribution 
  then this problem does not arise.

A Google search reveals a number of similar problems, but with no 
explanation other than possible typing errors.

Any suggestions as to why this is happening?

Thanks in advance,

Jonathan.

Maybe Mandrake has thrown some patches in to make it work?

 That convenience thing, look at man modprobe:

 modprobe intelligently adds or removes a module from the Linux kernel:
note  that  for  convenience,there  is  no  difference  between  _  and
- in module names.

What definition of convenience led to this?

In that spirit, should fs now interpret backslash as a directory separator?
Having to remember the difference is SO inconvenient.
