That would be a valid point for debugging messages. However, we are talking about messages to users here. I maintain that the additional 20 characters in:
Feb 21 00:12:13 gx110 kernel: drivers/isdn/gigaset/i4l.c: ISDN_CMD_SETL3: invalid protocol 42
as opposed to:
Feb 21 00:12:13 gx110 kernel: gigaset: ISDN_CMD_SETL3: invalid protocol 42
do not provide any useful information for that clientele. They just push the actual interesting information farther to the right, in this case even causing a line wrap.
If I want to include the function name in the message I can (and indeed I quite frequently do), but this only makes the clutter worse if the macros force the source path on me regardless.
