Hello Joe,

As one can see in be_main.h the "level" argument of macro beiscsi_log() 
is ignored for log levels KERN_EMERG, KERN_ALERT, KERN_CRIT and
KERN_ERR. So for these log levels beiscsi_log() is a synonym of 
shost_printk(). Have you considered to replace beiscsi_log() with 
shost_printk() for these log levels and additionally to change 
beiscsi_log() for the other log levels into pr_debug()? pr_debug() 
statements namely already can be enabled and disabled at runtime. If the 
BEISCSI_LOG_* log category would be embedded in the log text that would 
allow to eliminate the phba->attr_log_enable structure member. 
Additionally, pr_debug() has a facility for displaying the source file 
name and the line number. That would allow to leave out __LINE__ from 
be2iscsi log statements. I don't think it is useful to have that line 
number in non-debug be2iscsi log statements.

Thanks,

Bart.
