+But this patch is not going to get upstreamed because it got fixed in Linux kernel:
+a85cbe6159ff "uapi: move constants from <linux/kernel.h> to <linux/const.h>"
+
+This patch was also backported to stable and LTS versions,
+which we use since buildroot 54584d233b "{linux, linux-headers}: bump
+5.{4, 10}.x 4.{4, 9, 14, 19} series".
+We just wait for all musl based toolchains to be rebuilt. ]
