ebd173beb8 ext4: move procfs registration code to fs/ext4/sysfs.c 
This allows us to refactor the procfs code, which saves a bit of
compiled space.  More importantly it isolates most of the procfs
support code into a single file, so it's easier to #ifdef it out if
the proc file system has been disabled.

b579901882 ext4: move sysfs code from super.c to fs/ext4/sysfs.c 
Also statically allocate the ext4_kset and ext4_feat objects, since we
only need exactly one of each, and it's simpler and less code if we
drop the dynamic allocation and deallocation when it's not needed.
