Subject: [PATCH 1/1] vhost_task: Fix vhost_task_create return value
Date: Wed, 22 Mar 2023 13:56:05 -0500	[thread overview]
Message-ID: <20230322185605.1307-1-michael.christie@oracle.com> (raw)

vhost_task_create is supposed to return the vhost_task or NULL on
failure. This fixes it to return the correct value when the allocation
of the struct fails.

Fixes: 77feab3c4156 ("vhost_task: Allow vhost layer to use copy_process") # mainline only
Reported-by: syzbot+6b27b2d2aba1c80cc13b@syzkaller.appspotmail.com
