From 44ef38f9a2af8644c24ace6cbe1132dc70174c39 Mon Sep 17 00:00:00 2001 From: "Matthew R. Ochs" Date: Tue, 9 Aug 2016 18:39:30 -0500 Subject: scsi: cxlflash: Cache owning adapter within context The context removal routine requires access to the owning adapter structure to reset the context within the AFU as part of the tear down sequence. In order to support kref adoption, the owning adapter must be accessible from the release handler. As the kref framework only provides the kref reference as the sole parameter, another means is needed to derive the owning adapter. As a remedy, the owning adapter reference is saved off within the context during initialization. Signed-off-by: Matthew R. Ochs Acked-by: Manoj N. Kumar Signed-off-by: Martin K.
