From 9227c33de80ac01f269ed33624990ce84358e419 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 1 Apr 2006 19:21:04 +0200 Subject: [PATCH] move ->eh_strategy_handler to the transport class Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.
