Re: [Xen-devel] Re: [PATCH] [vTPM] Not building vTPM frontend as module

I suggest you add __unsafe(THIS_MODULE) to the end of your module_init

the kernel log explaining why.
If a module_init() is present but a module_exit() is not then you
cannot
unload the module.
(unless you enable CONFIG_MODULE_FORCE_UNLOAD and use rmmod's --force
option, in which case your kernel become tainted)
Even better. We should be using this for netback and blkback too in
that case.
