vmscan: rename sc.may_swap to may_unmap
sc.may_swap does not only influence reclaiming of anon pages but pages mapped into pagetables in general, which also includes mapped file pages. In shrink_page_list(): if (!sc->may_swap && page_mapped(page)) goto keep_locked; For anon pages, this makes sense as they are always mapped and reclaiming them always requires swapping. But mapped file pages are skipped here as well and it has nothing to do with swapping. The real effect of the knob is whether mapped pages are unmapped and reclaimed or not. Rename it to `may_unmap' to have its name match its actual meaning more precisely.
