+ *

+ *    unregister_netdevice_many                   kernfs_seq_start
+ *    device_del / kobject_put                      kernfs_get_active (kn->active++)
+ *    kernfs_drain                                sysfs_kf_seq_show

+ *       kn->active == KN_DEACTIVATED_BIAS)       -> waits on CPU 0 to release
+ *    -> waits on CPU 1 to decrease kn->active       the rtnl lock.
+ *
+ * The historical fix was to use rtnl_trylock with restart_syscall to bail out
+ * of sysfs operations when the lock couldn't be taken. This fixed the above
+ * issue as it allowed CPU 1 to bail out of the ABBA situation.
+ *
+ * But it came with performances issues, as syscalls are being restarted in
+ * loops when there was contention on the rtnl lock, with huge slow downs in
+ * specific scenarios (e.g. lots of virtual interfaces created and userspace
+ * daemons querying their attributes).
+ *
+ * The idea below is to bail out of the active kernfs_node protection
+ * (kn->active) while trying to take the rtnl lock.
+ *
+ * This replaces rtnl_lock() and still has to be used with rtnl_unlock(). The
+ * net device is guaranteed to be alive if this returns successfully.
