I still get
akpm3:/usr/src/25/tools/testing/radix-tree> make
cc -I. -I../../include -g -O2 -Wall -D_LGPL_SOURCE -fsanitize=address -c -o main.o main.c
In file included from ./linux/../../../../include/linux/radix-tree.h:28:0,
from ./linux/radix-tree.h:6,
from main.c:10:
./linux/rcupdate.h:5:10: fatal error: urcu.h: No such file or directory
#include <urcu.h>
lots of breakage here :(
