Subject: [PATCH 15/25] afs: Print the operation debug_id when logging an unexpected data version
Date: Wed, 20 Jan 2021 22:24:21 +0000	[thread overview]
Message-ID: <161118146111.1232039.11398082422487058312.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <161118128472.1232039.11746799833066425131.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.
