From 1bab0de0274fbe8c8ac92179e6705584c55ed169 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 27 Aug 2015 14:16:54 +0200 Subject: dm-mpath, scsi_dh: don't let dm detach device handlers While allowing dm-mpath to attach device handlers is a functionality we need for backwards compatibility reason there is no reason to reference count them and detach them if dm-mpath stops using the device for some reason. If the device handler works for the given device it can just stay attached, and we can take the retain_hw_handler codepath.
