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.

What:	mount/umount uevents

When:	February 2007

Why:	These events are not correct, and do not properly let userspace know
