Maxime Coquelin e706675bee vduse: Use proper spinlock for IRQ injection ... [ Upstream commit 7ca26efb09 ] The IRQ injection work used spin_lock_irq() to protect the scheduling of the softirq, but spin_lock_bh() should be used. With spin_lock_irq(), we noticed delay of more than 6 seconds between the time a NAPI polling work is scheduled and the time it is executed.
