Subject: [PATCH v3 08/10] liveupdate: Remove liveupdate_test_unregister()
Date: Fri, 27 Mar 2026 03:33:32 +0000	[thread overview]
Message-ID: <20260327033335.696621-9-pasha.tatashin@soleen.com> (raw)
In-Reply-To: <20260327033335.696621-1-pasha.tatashin@soleen.com>

Now that file handler unregistration automatically unregisters all
associated file handlers (FLBs), the liveupdate_test_unregister()
function is no longer needed. Remove it along with its usages
and declarations.
