Subject: [PATCH v4 04/11] KVM: arm64: nVHE: Use NULL to reset the trace buffer backing pointer
Date: Tue, 1 Sep 2026 15:03:19 +0100 [thread overview]
Message-ID: <20260901140326.3812068-5-fuad.tabba@linux.dev> (raw)
In-Reply-To: <20260901140326.3812068-1-fuad.tabba@linux.dev>
bpages_backing_start is a pointer; resetting it to plain 0 triggers a
sparse warning.
No functional change intended.
