This patch makes it indicate the proper error value when it fails. [ 25.932367] nvme nvme0: failed to mark controller CONNECTING [ 25.932369] nvme nvme0: Removing after probe failure status: -16 This situation is able to be easily reproduced by: root at target:~# rmmod nvme && modprobe nvme && rmmod nvme Signed-off-by: Minwoo Im --- drivers/nvme/host/pci.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/nvme/host/pci.c b/drivers/nvme/host/pci.c index 5c051a8470d4..fa0a1983d6a5 100644 --- a/drivers/nvme/host/pci.c +++ b/drivers/nvme/host/pci.c @@ -2524,6 +2524,7 @@ static void nvme_reset_work(struct work_struct *work) if (!nvme_change_ctrl_state(&dev->ctrl, NVME_CTRL_CONNECTING)) { dev_warn(dev->ctrl.device, "failed to mark controller CONNECTING\n"); + result = -EBUSY; goto out; } -- 2.21.0
