Subject[PATCH] nilfs2: use default_groups in kobj_type
Date
There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the nilfs2 code to use default_groups field which has been
the preferred way since aa30f47cf666 ("kobject: Add support for default
attribute groups to kobj_type") so that we can soon get rid of the
obsolete default_attrs field.
