From 291b9d73681f3e0123b8954eb20be22342987afc Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Mon, 13 Feb 2017 11:16:02 -0800 Subject: Improve sparse documentation Add documentation of -DCONFIG_SPARSE_RCU_POINTER. I started to add documentation of -D__CHECK_ENDIAN__ as well, but discovered I'm too late; that's now enabled by default.
