Summary

All vm_object_page_remove() callers, except the LinuxKPI, free swap
space when removing a range of pages from an object. I believe the
omission in the LinuxKPI is a bug: looking at the Linux implementation,
pages in the range are purged from the swap cache.

Isn't the round_page() redundant given the above "if" statement?

I believe you are right. I created D25400 for this and the other nit you pointed out.
