+Subject: [PATCH] net: Use __kernel_clockid_t in uapi net_stamp.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Herton reports the following error when building a userspace program that
+includes net_stamp.h:
+
+ In file included from foo.c:2:
+ /usr/include/linux/net_tstamp.h:158:2: error: unknown type name
+ ‘clockid_t’
+   clockid_t clockid; /* reference clockid */
+   ^~~~~~~~~
+
+Fix it by using __kernel_clockid_t in place of clockid_t.
+
+Fixes: 80b14dee2bea ("net: Add a new socket option for a future transmit time.")
