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
