[PATCH] kernel/rcupdate.c: make the exports EXPORT_SYMBOL_GPL
The gpl exports need to be put back. Moving them to GPL -- but in a
measured manner, as I proposed on this list some months ago -- is fine.
Changing these particular exports precipitously is most definitely -not-
fine. Here is my earlier proposal:
http://marc.theaimsgroup.com/?l=linux-kernel&m=110520930301813&w=2
See below for a patch that puts the exports back, along with an updated
version of my earlier patch that starts the process of moving them to GPL.
I will also be following this message with RFC patches that introduce two
(EXPORT_SYMBOL_GPL) interfaces to replace synchronize_kernel(), which then
becomes deprecated.
