NVMe: Need to lock queue during interrupt handling
If we're sharing a queue between multiple CPUs and we cancel a sync I/O, we must have the queue locked to avoid corrupting the stack of the thread that submitted the I/O. It turns out this is the same locking that's needed for the threaded irq handler, so share that code. Signed-off-by: Matthew Wilcox <[email protected]>
