Gleb Smirnoff 5dba303d01 Use bogus_page to properly reduce number of I/Os in sendfile(2). The new ... sendfile_swapin() loop works this way: - Find first invalid page in the request. - Do vm_pager_has_page() and get count of pages, that can be taken in single I/O. - Trim valid pages from the end of the request. - Cycle through the request and substitute to bogus_page all valid pages that are in the middle of the request. - After I/O launched (pager copies array of pages into buf(9), it is important to restore proper page pointers with help vm_page_lookup(). Count bogus pages used and report them in sendfile stats.		2016-11-17 21:02:55 +00:00
