Subject: [patch 01/25] debugobjects: Delete a piece of redundant code

From: Zhen Lei <thunder.leizhen@...wei.com>

The statically allocated objects are all located in obj_static_pool[],
the whole memory of obj_static_pool[] will be reclaimed later. Therefore,
there is no need to split the remaining statically nodes in list obj_pool
into isolated ones, no one will use them anymore. Just write
INIT_HLIST_HEAD(&obj_pool) is enough. Since hlist_move_list() directly
discards the old list, even this can be omitted.
