+Subject: tools headers UAPI: Sync linux/in.h copy with the kernel sources
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Arnaldo Carvalho de Melo <acme@redhat.com>
+
+commit 1792a59eab9593de2eae36c40c5a22d70f52c026 upstream.
+
+To pick the changes in:
+
+  321827477360934d ("icmp: don't send out ICMP messages with a source address of 0.0.0.0")
+
+That don't result in any change in tooling, as INADDR_ are not used to
+generate id->string tables used by 'perf trace'.
+
+This addresses this build warning:
+
+  Warning: Kernel ABI header at 'tools/include/uapi/linux/in.h' differs from latest version at 'include/uapi/linux/in.h'
