To test whether the debugging channel xxx is
enabled, use the TRACE_ON
, WARN_ON
,
FIXME_ON
, or ERR_ON
macros. For
example:
if(TRACE_ON(atom)){ ...blah... }You should normally need to test only if TRACE_ON, all the others are very seldomly used. With careful coding, you can avoid the use of these macros, which is generally desired.
