In the kdocs of kmap_local_folio() there is a an ambiguous sentence which suggests to use this API "only when really necessary". On the contrary, since kmap() and kmap_atomic() are deprecated, both kmap_local_folio(), as well as kmap_local_page(), must be preferred to the previous ones. Therefore, remove the above-mentioned sentence. Cc: Ira Weiny <ira.weiny@xxxxxxxxx> Cc: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx> Signed-off-by: Fabio M.
