The PHY interrupts are now handled in a threaded interrupt handler, which can sleep. The work queue is no longer needed, phy_change() can be called directly. Additionally, none of the callers of phy_mac_interrupt() did so in interrupt context, so fully remove theI did intend to call it from interrupt context (from the ravb driver).quoted
work queue, and document that phy_mac_interrupt() should not be called in interrupt context.It was intentionally made callable from the interrupt context, I'd prefer if you wouldn't change that.OTOH, it's still not very handy to call because of the 'new_link' parameter which I'm not sure I can provide...Hi Sergei If there is a need for it, i will leave the work queue and keep this code unchanged.Let's hear what Florian says...
The intent is really to have phy_mac_interrupt() callable from hard IRQ context, not that this matters really too much because link events already occur in the slow path, but it's nice to have that property retained IMHO. -- Florian
