From 2eafd72939fda6118e27d3ee859684987f43921b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 3 Oct 2015 15:32:55 +0200 Subject: target: use per-attribute show and store methods This also allows to remove the target-specific old configfs macros, and gets rid of the target_core_fabric_configfs.h header which only had one function declaration left that could be moved to a better place.
