Do these changes work without the matching xennet changes?
Do the xennet changes work without these changes?
(i.e. is it safe to apply these without the xennet patches or the xennet patches
without these patches?)

Subject: [PATCH 0/5] Rundown MRSW lock and device removal fixes
Patches 1 and 2 are fixes for various lockups encountered during
surprise removal.
Patch 3 is an annotation prerequisite for Patch 4, which replaces the
current MRSW lock with a simpler one.
Patch 5 is only for debugging purposes.
To be used together with matching Xennet surprise removal patches.
Tu Dinh (5):
Check Fragment->Entry before calling RevokeForeignAccess
Watch BACKEND/state key for eject status
Update IRQL annotations
Implement rundown-based MRSW lock
Trace worker thread wake events
