Subject: [PATCH 2/8] signal: Export ignore_signals
Date: Thu, 16 Sep 2021 16:20:45 -0500	[thread overview]
Message-ID: <20210916212051.6918-3-michael.christie@oracle.com> (raw)
In-Reply-To: <20210916212051.6918-1-michael.christie@oracle.com>

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.
