[Xen-devel] [RFC] Cleaning up SCM debug

[Anthony Liguori <aliguori@xxxxxxxxxx>]

Hi,

public/acm.h defines both an ACM_DEBUG flag and a printkd function that, 
if ACM_DEBUG is defined will convert to a printk.  public/acm.h is 
included by userspace applications where printk isn't necessarily 
meaningful.  Furthermore, it appears ACM_DEBUG is only used within Xen 
anyway so making it apart of the public headers doesn't make much sense.
Therefore, I'd like to move ACM_DEBUG and printkd into acm/acm_core.h.  
While at it, it seems like a good idea to change the printkd into either 
one of the existing Xen debug macros or to get rid of it altogether.
I wanted to check first to see if there was an emerging standard macro 
(a quick glance shows printk, DPRINTK, PRINT, and I'm sure there are at 
least a few more).  Recommendations are appreciated.
Regards,

Anthony Liguori
