+	  the sync_tick callback was running at the same time the dynamic
+	  local span was destroyed. It was possible for

+	  ztdeth_exit() symetrical with ztdeth_init() and fix race on
+	  unload. Minor change to follow generally recommended practice.
+	  Prevents new packets from being queued up for devices when they
+	  are about to be cleaned up. Also clean up any skbs that may still
+	  be on the queue after unloading. Also closes anoter potential
+	  kernel oops on module unload. It was possible to delete the
+	  private structure while the master span process was running. The
+	  result was an attempt to page memory from interrupt context. Make
+	  sure that the pvt function is set and cleared under the zlock.
+	  Also do not assume that the pvt pointer is valid in
+	  ztdeth_transmit. Signed-off-by: Shaun Ruffell

+	* drivers/dahdi/dahdi_dynamic.c: dahdi_dynamic: Close race on
+	  unload if red alarm timer was running when unloaded. I saw a
+	  kernel oops that was the result of the timer running after the
+	  dahdi_dynamic module was unloaded. Now we wait for the timer to
+	  complete, and then delete it again in case it reactivated itself.

+
+	* drivers/dahdi/dahdi_dynamic.c: dahdi_dynamic: Remove calls to
+	  __module_get(). The board drivers are the ones calling the
+	  unregister function, and therefore we do not need to worry about
+	  them unloading while calling the destroy callback. When
+	  destroying spans with the ioctl, replace __module_get() with
+	  try_module_get. This avoids hitting a BUG in module_get on kernel
+	  versions < 2.6.29. ALSO move the call to try_module_get out of
+	  the dahdi_dynamic_release function and into destroy. This way if
+	  the destroy callback isn't called because the dynamic driver is
+	  unloading the dynamic device can be left on the list to be
+	  cleaned up by the dahdi_dynamic_unregister_driver function().

+	  function pointer, register a dahdi_dynamic_ops structure that
+	  contains the owner as well as the ioctl callback. This way
+	  dahdi.ko can bump up the reference count on dahdi_dynamic.ko
+	  before calling the ioctl callback. Also, use the registration
+	  mutex to guard against the module being unloaded between the time
+	  the structure pointer was checked, and the module reference is
+	  taken. Signed-off-by: Shaun Ruffell <sruffell@digium.com> Origin:

+	  [1], I inadvertently changed the debounce interval of the RINGOFF
