From: Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx> This patch has been added to the 4.1 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 7e040726850a106587485c21bdacc0bfc8a0cbed ] [resend due to me forgetting to cc: linux-api the first time around I posted these back on Feb 23] From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> For some reason these values are not in the uapi header file, so any libc has to define it themselves. To prevent them from needing to do this, just have the kernel provide the correct values.
