From 6604b05763515f6329bf508ff1284651ebffc33e Mon Sep 17 00:00:00 2001 From: Ilya Leoshkevich Date: Tue, 5 Mar 2024 12:09:44 +0000 Subject: gdbstub: Call gdbserver_fork() both in parent and in child MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The upcoming follow-fork-mode child support requires post-fork message exchange between the parent and the child. Prepare gdbserver_fork() for this purpose. Rename it to gdbserver_fork_end() to better reflect its purpose.
