-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
