From 3cb7eda5806838c4ec9b0387c489e0e7d8101a44 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 13 Mar 2020 13:36:01 +0000 Subject: [PATCH] afs: Fix some tracing details commit 4636cf184d6d9a92a56c2554681ea520dd4fe49a upstream. Fix a couple of tracelines to indicate the usage count after the atomic op, not the usage count before it to be consistent with other afs and rxrpc trace lines. Change the wording of the afs_call_trace_work trace ID label from "WORK" to "QUEUE" to reflect the fact that it's queueing work, not doing work.
