This patch set will provide a framework and help to create attributes
from the structure btrfs_fs_devices which are available even before
fs_info is created. So by moving the parent kobject super_kobj from
fs_info to btrfs_fs_devices, it will help to create attributes
from the btrfs_fs_devices as well.
Just to note, this does not change any of the existing btrfs sysfs
external kobject names and its attributes and not even the life
cycle of them. Changes are internal only. And to ensure the same,
this path has been tested with various device operations and,
checking and comparing the sysfs kobjects and attributes with
sysfs kobject and attributes with out this patch, and they remain
same. These test cases are added to the progs as test-btrfs-devmgt.sh,
its patch is below as well.
v1->v2:
. adds fresh set of patches from 12 to 24 to support seed fsids
on btrfs sysfs layout and the related frame work changes
. the patches 1 to 12 has no changes from the previous submit
