+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

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

+What:  Usage of invalid timevals in setitimer
+When:  March 2007
+Why:   POSIX requires to validate timevals in the setitimer call. This
+       was never done by Linux. The invalid (e.g. negative timevals) were
+       silently converted to more or less random timeouts and intervals.
+       Until the removal a per boot limited number of warnings is printed
+       and the timevals are sanitized.

+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.
