Subject: [PATCH v7 01/29] mm: rename pmd_to_softleaf_folio() to pmd_softleaf_to_folio()
Date: Mon, 14 Sep 2026 04:41:53 -0700 [thread overview]
Message-ID: <20260914114320.12988-2-usama.arif@linux.dev> (raw)
In-Reply-To: <20260914114320.12988-1-usama.arif@linux.dev>
pmd_to_softleaf_folio() reads as if it converted a PMD into a folio. What
it does is decode the softleaf entry stored in the PMD and return the
folio that entry references - the direction softleaf_to_folio() already
spells out.
No functional change intended.
