In a generic sense that is true. Take into account that when you call
from a module you are just calling from Linux, and Linux is just the
lowest priority real time task. So if you call a non "task_switching"
function it will be just a normal call while if it is a switching one it
will switch. Clearly you must have a real time scheduler installed.

There can be however glitches has there is often an implicit assumption
that many functions will/should be never used from Linux, so they have
not been tested for such a use.

Ciao, Paolo.
