From 0ff18e3734c248fa516b4be942b1196832ee936c Mon Sep 17 00:00:00 2001 From: Fengguang Wu Date: Wed, 9 Oct 2013 09:26:21 +0800 Subject: kobject: show debug info on delayed kobject release Useful for locating buggy drivers on kernel oops. It may add dozens of new lines to boot dmesg. DEBUG_KOBJECT_RELEASE is hopefully only enabled in debug kernels (like maybe the Fedora rawhide one, or at developers), so being a bit more verbose is likely ok.
