Subject: [PATCH v7 20/31] afs: Print the operation debug_id when logging an unexpected data version
Date: Fri, 23 Apr 2021 14:32:34 +0100 [thread overview]
Message-ID: <161918475483.3145707.16895916870392318058.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <161918446704.3145707.14418606303992174310.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.
