Subject: [PATCH 5.10 066/111] 9p: explicitly deny setlease attempts
Date: Tue, 14 May 2024 12:20:04 +0200 [thread overview]
Message-ID: <20240514100959.642740743@linuxfoundation.org> (raw)
In-Reply-To: <20240514100957.114746054@linuxfoundation.org>
5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jlayton@kernel.org>
[ Upstream commit 7a84602297d36617dbdadeba55a2567031e5165b ]
9p is a remote network protocol, and it doesn't support asynchronous
notifications from the server. Ensure that we don't hand out any leases
since we can't guarantee they'll be broken when a file's contents
change.
