Subject: [PATCH v1 04/11] KVM: arm64: nVHE: Use NULL to reset the trace buffer backing pointer
Date: Mon, 20 Jul 2026 17:13:36 +0100 [thread overview]
Message-ID: <20260720161343.1367007-5-fuad.tabba@linux.dev> (raw)
In-Reply-To: <20260720161343.1367007-1-fuad.tabba@linux.dev>
bpages_backing_start is a pointer; resetting it to plain 0 triggers a
sparse warning.
No functional change intended.
