From 72f1c55adf70fd08ceac6b67455238db2014894a Mon Sep 17 00:00:00 2001 From: "Fabio M. De Francesco" Date: Thu, 28 Jul 2022 17:48:43 +0200 Subject: highmem: delete a sentence from kmap_local_page() kdocs kmap_local_page() should always be preferred in place of kmap() and kmap_atomic(). "Only use when really necessary." is not consistent with the Documentation/mm/highmem.rst and these kdocs it embeds. Therefore, delete the above-mentioned sentence from kdocs.
