Subject: [PATCH net-next 0/6] Devlink cleanup for delay event series

From: Leon Romanovsky <leonro@...dia.com>

Hi, 

Jakub's request to make sure that devlink events are delayed and not
printed till they fully accessible [1] requires us to implement delayed
event notification system in the devlink.

In order to do it, I moved some of my patches (xarray e.t.c) from the future
series to be before "Move devlink_register to be near devlink_reload_enable" [2].

That allows us to rely on DEVLINK_REGISTERED xarray mark to decide if to print
event or not.

Other patches are simple cleanup which is needed anyway.

Next in the queue:
 * Delay event series
 * Move devlink_register to be near devlink_reload_enable"
 * Extension of devlink_ops to be set dynamically
 * devlink_reload_* delete
 * Devlink locks rework to user xarray and reference counting
 * ????

Thanks
