Subject: [PATCH] [PATCH] kill unushed __put_task_struct_cb
Somehow in the midst of dotting i's and crossing t's during
the merge up to rc1 we wound up keeping __put_task_struct_cb
when it should have been killed as it no longer has any users.
Sorry I probably should have caught this while it was
still in the -mm tree.
Having the old code there gets confusing when reading
through the code and trying to understand what is
happening.
