From e4c9eabc931b2a6c80fcdece5eb5051d8aec92f8 Mon Sep 17 00:00:00 2001 From: "Fabio M. De Francesco" Date: Sat, 8 Jul 2023 14:16:18 +0200 Subject: Documentation/highmem: Add information about kmap_local_folio() The differences between kmap_local_page() and kmap_local_folio() consist only in the first taking a pointer to a page and the second taking two arguments, a pointer to a folio and the byte offset within the folio which identifies the page.
