try_to_unmap currently has multiple modi (migration, munlock, normal unmap) which are selected by magic flag variables. The logic is not very straight forward, because each of these flag change multiple behaviours (e.g. migration turns off aging, not only sets up migration ptes etc.) Also the different flags interact in magic ways. A later patch in this series adds another mode to try_to_unmap, so this becomes quickly unmanageable. Replace the different flags with a action code (migration, munlock, munmap) and some additional flags as modifiers (ignore mlock, ignore aging). This makes the logic more straight forward and allows easier extension to new behaviours. Change all the caller to declare what they want to do. This patch is supposed to be a nop in behaviour. If anyone can prove it is not that would be a bug. Cc: Lee.Schermerhorn@hp.com Cc: npiggin@suse.de Signed-off-by: Andi Kleen <ak@linux.intel.com> |
