parentbtrfs: sysfs: add removal calls for debug/ (diff)
btrfs: sysfs: make UUID/debug have its own kobject
Btrfs only allowed attributes to be exposed in debug/. Let's let other groups be created by making debug its own kobject. This also makes the per-fs debug options separate from the global features mount attributes. This seems to be needed as sysfs_create_files() requires const struct attribute * while sysfs_create_group() can take struct attribute *. This seems nicer as per file system, you'll probably use to_fs_info().
