Subject: [PATCH v8 01/30] mm: rename pmd_to_softleaf_folio() to pmd_softleaf_to_folio()
Date: Fri,  2 Oct 2026 02:52:15 -0700	[thread overview]
Message-ID: <20261002095503.3585565-2-usama.arif@linux.dev> (raw)
In-Reply-To: <20261002095503.3585565-1-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.
