Subjectdm-writeboost: unusual refcount on Raspberry Pi
Hi, all

I am trying to run writeboost on a tiny ARM machine, Raspberry Pi.
writeboost can compile without any error nor warning but
it doesn't even start ctr.

What I do before running `dmsetup create` is
# modprobe dm-mod
# insmod dm-writeboost.ko

After these two commands, lsmod looks insane.
I suppose dm_writeboost module's refcount should be 0, not -1 (2147483647).
Nonetheless, dmesg doesn't indicate anything at all.
If I try to make a writeboost device after this,
it hangs up the whole system.

I have no idea what is happening in my system.
If you know something about this, please help me.
