-This problem was created by the upstream commit 78708b7c8c
-After applying the commit, it will send SIGINT to the process group(-signal_pid).
-But if we use gdbserver send SIGINT, and the attached process is not a process
-group leader, then the "kill (-signal_pid, SIGINT)" returns error and fails  to
-interrupt the attached process.

+Subject: [PATCH] gdbserver ctrl-c handling
+
+This problem was created by the upstream commit 78708b7c8c
+After applying the commit, it will send SIGINT to the process
+group(-signal_pid).
+But if we use gdbserver send SIGINT, and the attached process is not a
+process
+group leader, then the "kill (-signal_pid, SIGINT)" returns error and
+fails  to
+interrupt the attached process.
