Subject: [PATCH for-6.2 v3 04/12] job: Force-cancel jobs in a failed transaction
Date: Fri,  6 Aug 2021 11:38:51 +0200	[thread overview]
Message-ID: <20210806093859.706464-5-mreitz@redhat.com> (raw)
In-Reply-To: <20210806093859.706464-1-mreitz@redhat.com>

When a transaction is aborted, no result matters, and so all jobs within
should be force-cancelled.
