Subject: [PATCH v4 17/28] afs: Print the operation debug_id when logging an unexpected data version
Date: Wed, 10 Mar 2021 16:58:16 +0000 [thread overview]
Message-ID: <161539549628.286939.15234870409714613954.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <161539526152.286939.8589700175877370401.stgit@warthog.procyon.org.uk>
Print the afs_operation debug_id when logging an unexpected change in the
data version. This allows the logged message to be matched against
tracelines.
