+What: remove EXPORT_SYMBOL(kernel_thread)
+When: August 2006
+Files: arch/*/kernel/*_ksyms.c
+Why: kernel_thread is a low-level implementation detail. Drivers should
+ use the <linux/kthread.h> API instead which shields them from
+ implementation details and provides a higherlevel interface that
+ prevents bugs and code duplication

What: EXPORT_SYMBOL(lookup_hash)
When: January 2006
Why: Too low-level interface. Use lookup_one_len or lookup_create instead.
---------------------------
+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
