- Subject: [PATCH 11/11] 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.
