Subject: Is __xfrm_lookup always on non-atomic context ?

Hi all,

I'm using XFRM for tunneling payload traffic on Dual Stack Mobility application.
However, if correspondent XFRM states to XFRM policy's templates have
not been registered yet, It's possible the current process wait for
them, using a wait queue.
But what if this function is not being called on atomic context (e.g. softirq) ?

Thanks in advance,
Eduardo Panisset.
