+Subject: [PATCH] clone.2, fork.2: Document ERESTARTNOINTR error code
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Since Linux 2.6.17, clone and fork syscalls return ERESTARTNOINTR
+when interrupted by a signal before newly created process is added
+to its process group.
+This error code can only be seen by ptrace at syscall exit tracing.
+
+The information was obtained from kernel source code:
+http://bit.ly/24xdofn
