Here is some diff comparing output between the sparse 0.2 and the tip of git.
-mm/mmap.c:1631:2: warning: context imbalance in 'expand_stack' - different lock
contexts for basic block
+include/linux/rmap.h:55:2: warning: context imbalance in 'expand_stack' - diffe
The change is introduced by the inline annotate instruction,
which mark the bb->pos to the inline function.
This change make it back to the caller position.
