[PATCH 07/29] {linux,bsd}-user: Pass pid to gdbserver_fork()


From: Alex Bennée
Subject: [PATCH 07/29] {linux,bsd}-user: Pass pid to gdbserver_fork()
Date: Tue, 5 Mar 2024 12:09:43 +0000

From: Ilya Leoshkevich <iii@linux.ibm.com>

The upcoming follow-fork-mode child support requires knowing the child
pid. Pass it down.
