Goncalves" To: Sebastian Andrzej Siewior , Steven Rostedt , Stable RT List Subject: Question about the maintenance of OOT RT patches for LTS releases (v12.x and v18.x) Message-ID: Precedence: bulk X-Mailing-List: stable-rt@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline X-Scanned-By: MIMEDefang 3.4.1 on 10.30.177.93 Hello! The question is simple: Should we have somebody maintaining the OOT RT patches for v12.x and v18.x, the LTS versions that already have PREEMPT_RT in-tree? As we still have a few OOT patches, after a while, people using PREEMPT_RT on those versions may encounter conflicts trying to apply the old patches. And as those patches are not in-tree, the fixes won't probably be routed via Stable. Best regards, Luis
