From: "Matthew R. Ochs" <mrochs@xxxxxxxxxxxxxxxxxx> With the removal of the static private command pool, the ability to 'complete' outstanding commands was lost. While not an issue for the commands originating outside the driver, internal AFU commands are synchronous and therefore have a timeout associated with them. To avoid a stale memory access, the tear down sequence needs to ensure that there are not any active commands before proceeding. As these internal AFU commands are rare events, the simplest way to accomplish this is detecting the activity and waiting for it to timeout. Signed-off-by: Matthew R. Ochs <mrochs@xxxxxxxxxxxxxxxxxx>
