linux.git/drivers/char/hw_random, branch v2.6.30 Linux kernel source tree virtio-rng: Remove false BUG for spurious callbacks 2009-04-24T20:28:30+00:00 Christian Borntraeger borntraeger@de.ibm.com 2009-04-23T07:12:59+00:00 e5b89542ea18020961882228c26db3ba87f6e608 The virtio-rng drivers checks for spurious callbacks. Since callbacks can be implemented via shared interrupts (e.g. PCI) this could lead to guest kernel oopses with lots of virtio devices.
