Subject: mm: adjust out-dated document of __GFP_NOFAIL
Date: Sat, 29 Aug 2026 02:58:47 +0000

Commit ee040cbd6e48 ("mm/page_alloc: don't warn about large allocations
with __GFP_NOFAIL") remove a warning on allocating large folio with
__GFP_NOFAIL, which was placed there by commit 903edea6c53f ("mm: warn
about illegal __GFP_NOFAIL usage in a more appropriate location and
manner").

While in that commit, it also documented this behavior which is out-dated
now.

Adjust the document to align to current code, and adjust the comment while
at it.
