Subject: [pve-devel] [PATCH librados2-perl 2/3] reset inherited signal handlers in child worker
Date: Tue, 8 Aug 2023 13:23:11 +0200 [thread overview]
Message-ID: <20230808112312.64667-3-f.ebner@proxmox.com> (raw)
In-Reply-To: <20230808112312.64667-1-f.ebner@proxmox.com>
For example, if pvestatd is the parent, the inherited signal handlers
from pvestatd, i.e. PVE/Daemon.pm's handlers would be invoked by the
child.
