      sysfs: crash debugging · ae87221d

      Print the name of the last-accessed sysfs file when we oops, to help track
      down oopses which occur in sysfs store/read handlers.  Because these oopses
      tend to not leave any trace of the offending code in the stack traces.

      Fix "notes" kobject leak
      
      It happens every rmmod if KALLSYMS=y and SYSFS=y.
      
      	# modprobe foo
      
      kobject: 'foo' (ffffffffa00743d0): kobject_add_internal: parent: 'module', set: 'module'
      kobject: 'holders' (ffff88017e7c5770): kobject_add_internal: parent: 'foo', set: '<NULL>'
      kobject: 'foo' (ffffffffa00743d0): kobject_uevent_env
      kobject: 'foo' (ffffffffa00743d0): fill_kobj_path: path = '/module/foo'
      kobject: 'notes' (ffff88017fa9b668): kobject_add_internal: parent: 'foo', set: '<NULL>'
      	  ^^^^^
      
      	# rmmod foo
      
      kobject: 'holders' (ffff88017e7c5770): kobject_cleanup
      kobject: 'holders' (ffff88017e7c5770): auto cleanup kobject_del
      kobject: 'holders' (ffff88017e7c5770): calling ktype release
      kobject: (ffff88017e7c5770): dynamic_kobj_release
      kobject: 'holders': free name
      kobject: 'foo' (ffffffffa00743d0): kobject_cleanup
      kobject: 'foo' (ffffffffa00743d0): does not have a release() function, it is broken and must be fixed.
      kobject: 'foo' (ffffffffa00743d0): auto cleanup 'remove' event
      kobject: 'foo' (ffffffffa00743d0): kobject_uevent_env
      kobject: 'foo' (ffffffffa00743d0): fill_kobj_path: path = '/module/foo'
      kobject: 'foo' (ffffffffa00743d0): auto cleanup kobject_del
      kobject: 'foo': free name
