V6:
- Remove the new d_compare() helper and export the d_same_name() instead
- Currently will use the EXPORT_SYMBOL_GPL instead.

V5:
- Fix the order of clearing the flag and hashtable

V4:
- Switch to use TASK_KILLABLE

V3:
- Removed WARN_ON_ONCE()/BUG_ON().
- Set the hashtable bit to 8.

V2:
- Add one dedicated spin lock to protect the list_add/del_rcu
- Other small fixes
