Re: [PATCH 10/17] nvme-pci: mark the namespaces dead earlier in nvme_remove

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




When we have a non-present controller there is no reason to wait in
marking the namespaces dead, so do it ASAP.  Also remove the superflous
call to nvme_start_queues as nvme_dev_disable already did that for us.

Don't you need to start the queues as well here?

nevermind, you call disable with shutdown=true


          nvme_dev_disable(dev, true);
