Subject: [PATCH 02/10] io_uring/zcrx: use folio_nr_pages() instead of shift operation
Date: Thu, 13 Nov 2025 10:46:10 +0000 [thread overview]
Message-ID: <083a8ca834fa7c5a0eedf355c684148b289b5135.1763029704.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1763029704.git.asml.silence@gmail.com>
From: Pedro Demarchi Gomes <pedrodemargomes@gmail.com>
folio_nr_pages() is a faster helper function to get the number of pages when
NR_PAGES_IN_LARGE_FOLIO is enabled.
