[PATCH 2/8] signal: Export ignore_signals

From: Mike Christie
Date: Thu Sep 16 2021 - 17:21:38 EST


The kthread API creates threads that ignore all signals by default so
modules like vhost that will move from that API to kernel_copy_process
will not be expecting them. This patch exports ignore_signals so those
modules can keep their existing behavior.
