Subject[PATCH] ext4: replace ktype default_attrs with default_groups
Date
The kobj_type default_attrs field is being replaced by the
default_groups field. Replace the default_attrs field in ext4_sb_ktype
and ext4_feat_ktype with default_groups. Use the ATTRIBUTE_GROUPS macro
to create ext4_groups and ext4_feat_groups.

This patch depends on a patch in the driver-core tree:
https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git/commit/?h=driver-core-next&id=aa30f47cf666111f6bbfd15f290a27e8a7b9d854

Greg KH can take this patch through the driver-core tree, or this patch
can wait a release cycle and go through the subsystem's tree, whichever
the subsystem maintainer is more comfortable with.
