[Cluster-devel] [Patch 16/44] libgfs2: Use __FUNCTION__ rather than __FILE__ for debug messages

Subject: [PATCH 16/44] libgfs2: Use __FUNCTION__ rather than __FILE__ for
 debug messages

This patch changes the debug output of gfs2-utils to use __FUNCTION__
rather than __FILE__.  The output file is much smaller.  Digging through
a 6.5GB output is better and faster than a 9GB output file.
