[Xen-devel] [PATCH] kobject: show debug info on delayed kobject release

[Fengguang Wu <fengguang.wu@xxxxxxxxx>]

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.
