function to zero out module ref count so module can be unloaded in 2.6 kernel?

function to zero out module ref count so module can be unloaded in 2.6 kernel?

[Vivek Dasgupta]

In 2.4 kernel one could check MOD_IN_USE and repeatedly call
MOD_DEC_USE_COUNT until the ref count drops to zero.

Is there a function in 2.6 kernel that would zero out the ref count so
that module can be unloaded ?

Need to implement ioctl for a driver to zero out the ref count.

Thanks
Vivek

*plonk*

Have you ever thought about a non-zero usage count? Maybe there actually
*are* still some users so unloading the module may crash the entire
system?! So don't kick-out your security gear, but dig out the real bugs
which seem to manifest in execssive users at your side...
