CWE-362
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
nvme-pci: fix race condition between reset and nvme_dev_disable()<br />
<br />
nvme_dev_disable() modifies the dev->online_queues field, therefore<br />
nvme_pci_update_nr_queues() should avoid racing against it, otherwise<br />
we could end up passing invalid values to blk_mq_update_nr_hw_queues().<br />
<br />
WARNING: CPU: 39 PID: 61303 at drivers/pci/msi/api.c:347<br />

<br />
Fix the bug by locking the shutdown_lock mutex before using<br />
dev->online_queues. Give up if nvme_dev_disable() is running or if<br />
it has been executed already.
