From 575ced1c8b0d3b578b933a68ce67ddaff3df9506 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 8 Dec 2020 01:25:39 -0500 Subject: mm/swap: Add folio_rotate_reclaimable() Convert rotate_reclaimable_page() to folio_rotate_reclaimable(). This eliminates all five of the calls to compound_head() in this function, saving 75 bytes at the cost of adding 15 bytes to its one caller, end_page_writeback(). We also save 36 bytes from pagevec_move_tail_fn() due to using folios there. Net 96 bytes savings. Also move its declaration to mm/internal.h as it's only used by filemap.c.
