Subject: mm: remove an ambiguous sentence from kmap_local_folio() kdocs
Date: Thu, 5 Jan 2023 13:04:24 +0100
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 exactly how it has
previously been done for the kmap_local_page() kdocs in commit
72f1c55adf70 ("highmem: delete a sentence from kmap_local_page() kdocs").
