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 Signed-off-by: Mike Christie <michael.christie@oracle.com> --- kernel/vhost_task.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
