+Subject: devlink: fix libc and kernel headers collision
+
+Since commit 2f1242efe9d ("devlink: Add devlink health show command") we
+use the sys/sysinfo.h header for the sysinfo(2) system call. But since
+iproute2 carries a local version of the kernel struct sysinfo, this
+causes a collision with libc that do not rely on kernel defined sysinfo
+like musl libc:
+
+In file included from devlink.c:25:0:
+.../sysroot/usr/include/sys/sysinfo.h:10:8: error: redefinition of 'struct sysinfo'
+ struct sysinfo {
+        ^~~~~~~
+In file included from ../include/uapi/linux/kernel.h:5:0,
+                 from ../include/uapi/linux/netlink.h:5,
+                 from ../include/uapi/linux/genetlink.h:6,
+                 from devlink.c:21:
+../include/uapi/linux/sysinfo.h:8:8: note: originally defined here
+ struct sysinfo {
+        ^~~~~~~
+
+Move the sys/sysinfo.h userspace header before kernel headers, and
+suppress the indirect include of linux/sysinfo.h.
