Can we get this bug fixed please?  Today?  It has been known about for more
than two months.

I can only assume that people don't use this feature much because this bug
will kill your kernel, every time.

Applying this:

--- a/drivers/net/bonding/bond_sysfs.c~bonding-locking-fix
+++ a/drivers/net/bonding/bond_sysfs.c
@@ -1111,8 +1111,6 @@ static ssize_t bonding_store_primary(str
-	rtnl_unlock();
 	return count;
 static DEVICE_ATTR(primary, S_IRUGO | S_IWUSR, bonding_show_primary, bonding_store_primary);

is better than doing nothing.
