Subject: [PATCH / RFC 0/2] spinlocks fixup in fec / m68knommu driver
Date: Thu, 27 Mar 2008 15:00:41 +0100 [thread overview]
Message-ID: <20080327140041.072611004@linutronix.de> (raw)
I got into this after turning on spinlock debugging.
Jeff: The dev->hard_start_xmit callback is always called from softirq
context so it is save to use spin_lock_irq(), right?
Greg: The isr (fec_enet_rx()) calls three functions. All
but fec_enet_rx() are grabbing the spinlock. Is this on purpose?
Sebastian
