Subject: [PATCH AUTOSEL 5.4 09/12] afs: Return -EAGAIN, not -EREMOTEIO, when a file already locked
Date: Wed, 14 Sep 2022 05:04:02 -0400 [thread overview]
Message-ID: <20220914090407.471328-9-sashal@kernel.org> (raw)
In-Reply-To: <20220914090407.471328-1-sashal@kernel.org>
From: David Howells <dhowells@redhat.com>
[ Upstream commit 0066f1b0e27556381402db3ff31f85d2a2265858 ]
When trying to get a file lock on an AFS file, the server may return
UAEAGAIN to indicate that the lock is already held. This is currently
translated by the default path to -EREMOTEIO.
Translate it instead to -EAGAIN so that we know we can retry it.
