Equivalent to dynamic_printk cmd line option with dynamic_debug ?

[Valentin Longchamp]

Hi,

I am working on support of an embedded system so I usually post and read 
the linux-arm mailing-list.

I used to find the dynamic_printk cmd line option very helpful to debug 
the "later" startup of my kernel. However, with dynamic_printk having 
been merged with dynamic_debug during the current merge window, I cannot 
do it anymore (or at least I haven't found how to in 
Documentation/dynamic-debug-howto.txt).

Is there a way to achieve it with the actual system? If not, I would say 
this would be a nice feature to add.

Thanks

Valentin
