Subject: [PATCH] dm-crypt: use folio_nr_pages() instead of shift operation
Date: Sat, 4 Oct 2025 00:19:12 -0300 [thread overview]
Message-ID: <20251004031912.50662-1-pedrodemargomes@gmail.com> (raw)
folio_nr_pages() is a faster helper function to get the number of pages when
NR_PAGES_IN_LARGE_FOLIO is enabled.
