Konstantin Belousov 77d6fd97ef Improve vm_object_scan_all_shadowed() to also check swap backing objects. ... As noted in the removed comment, it is possible and not prohibitively costly to look up the swap blocks for the given page index. Implement a swap_pager_find_least() function to do that, and use it to iterate simultaneously over both backing object page queue and swap allocations when looking for shadowed pages. Testing shows that number of new succesful scans, enabled by this addition, is small but non-zero. When worked out, the change both further reduces the depth of the shadow object chain, and frees unused but allocated swap and memory.
