This is a note to let you know that I've just added the patch titled refcount: change EXPORT_SYMBOL markings to the 4.11-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: refcount-change-export_symbol-markings.patch and it can be found in the queue-4.11 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From d557d1b58b3546bab2c5bc2d624c5709840e6b10 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Date: Thu, 4 May 2017 15:51:03 -0700 Subject: refcount: change EXPORT_SYMBOL markings From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> commit d557d1b58b3546bab2c5bc2d624c5709840e6b10 upstream. Now that kref is using the refcount apis, the _GPL markings are getting exported to places that it previously wasn't. Now kref.h is GPLv2 licensed, so any non-GPL code using it better be talking to some lawyers, but changing api markings isn't considered "nice", so let's fix this up.
