Subject: [PATCH v11 15/36] netfs: trace: Change the "clear" folio traces to "endwb"
Date: Wed,  2 Sep 2026 18:33:27 +0100	[thread overview]
Message-ID: <20260902173350.3468672-16-dhowells@redhat.com> (raw)
In-Reply-To: <20260902173350.3468672-1-dhowells@redhat.com>

Change the "clear" folio traces to "endwb" as it's more obvious what it
means.
