Summary

Define wrapper functions vm_map_entry_{succ,pred} to act as wrappers around entry->{next,prev} when those are used for ordered list traversal, and use those wrapper functions everywhere. Where the next field is used for maintaining a stack of deferred operations, #define defer_next to make that different usage clearer, and then use the 'right' pointer instead of 'next' for that purpose.

Event Timeline

Thanks. If you plan to commit this patch on its own, I'd suggest adding a comment above defer_next, even though that definition would be deleted shortly after.
