Subject: [PATCH v2 4/5] sunrpc: Prepare xs_connect() for taking NULL tasks
Date: Tue, 2 Feb 2021 13:42:43 -0500 [thread overview]
Message-ID: <20210202184244.288898-5-Anna.Schumaker@Netapp.com> (raw)
In-Reply-To: <20210202184244.288898-1-Anna.Schumaker@Netapp.com>
From: Anna Schumaker <Anna.Schumaker@Netapp.com>
We won't have a task structure when we go to change IP addresses, so
check for one before calling the WARN_ON() to avoid crashing.
