Can you help me find the required annotation that is already there but in the wrong file? This does seem to quiet a lockep warning in fs/dax.c, but I think we still have a related one in mm/memory.c: mm/memory.c:4204:5: warning: context imbalance in '__follow_pte_pmd' - different lock contexts for basic block Should we deal with this one as well?
