[Xen-devel] [PATCH] Fix recursive lock p2m lock acquisition in POD code
The POD code can take the p2m lock from inside a lookup. This causes a crash if anyone calls gfn_to_mfn* with the p2m lock held, which is quite a few places. Make the POD code understand that it may be called with the lock held, and DTRT about talking or releasing it.
