Subject: [PATCH v2 06/19] linux-headers: Update headers for v12 of in-place conversion kernel support
Date: Tue, 8 Sep 2026 15:48:26 -0500 [thread overview]
Message-ID: <20260908205236.838281-7-michael.roth@amd.com> (raw)
In-Reply-To: <20260908205236.838281-1-michael.roth@amd.com>
The kernel support is not yet upstream, so pull in the latest headers
for v12. This patch should be replaced with a full kernel header sync
once the kernel support lands.
