From f1d86b61fb6692c592e937dfb5069e4057855a3b Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Wed, 18 Sep 2013 17:21:34 +0200 Subject: s390/s390dbf: add debug_level_enabled() function Add the debug_level_enabled() function to check if debug events for a particular level would be logged. This might help to save cycles for debug events that require additional information collection.
