[PATCH v6 27/27] mm/filemap: Convert page wait queues to be folios

2021-03-31 Thread Matthew Wilcox (Oracle)
Reinforce that if we're waiting for a bit in a struct page, that's actually in the head page by changing the type from page to folio. Increases the size of cachefiles by two bytes, but the kernel core is unchanged in size. Signed-off-by: Matthew Wilcox (Oracle) --- fs/cachefiles/rdwr.c| 16 +
