-What:  remove EXPORT_SYMBOL(tasklist_lock)
-When:  August 2006
-Files: kernel/fork.c
-Why:   tasklist_lock protects the kernel internal task list.  Modules have
-       no business looking at it, and all instances in drivers have been due
-       to use of too-lowlevel APIs.  Having this symbol exported prevents
-       moving to more scalable locking schemes for the task list.
