Subject: [PATCH 2/5] lei: sto_done_request: add eval guard
Date: Tue, 14 Sep 2021 02:39:02 +0000	[thread overview]
Message-ID: <20210914023905.21410-3-e@80x24.org> (raw)
In-Reply-To: <20210914023905.21410-1-e@80x24.org>

Failures here can cause the lei-daemon event loop to break
since PktOp doesn't guard dispatch.  Add a guard here (and
not deeper in the stack) so we can use the $lei object to
report errors.
