[Xen-devel] RFC: removing hardcoded "modprobe blktap" in xencommons

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Hi Jan

Back before 4.3 release you complaint about the hardcoded modprobe for
blktap / blktap2 in xencommons script. I started to look into it this
week and tried to do this modprobe automatically in libxl (that's the
idea we discussed before 4.3 IIRC).

Unfortunately I didn't manage to find any canonical documents on how a
user space process can trigger a modprobe. I've looked at kernel
documentations and couldn't find any. Do you have any reference on how
to do that?

And, why do you think it is bad to have "modprobe blktap" in xencommons?
What about not removing it?


Wei.
