debugfs: adding helper for single seq_file

Quoted 20 lines · Arend van Spriel

The first patch was already posted earlier:

Message-ID: <[email protected]>

This series include changes in driver code to investigate potential code savings. As example used the ath9k driver as it has a fair amount of debugfs files. In this series it changes 7 debugfs entries to use seq_file and the helper function. Below the output of the size utility:

   text	   data	    bss	    dec	    hex	filename
 115968	   1225	     28	 117221	  1c9e5	original/ath9k.o
 113224	   1225	     28	 114477	  1bf2d	seq_file/ath9k.o
 111024	   1225	     28	 112277	  1b695	helper/ath9k.o

This series is for 3.19 kernel and applies to the driver-core-next branch of the driver-core repository. If needed the ath9k patches may be dropped for now and I will resubmit them to wireless-next once the debugfs patch has made it into linux-next.

Greg,

If you are happy with the debugfs change then feel free to merge the wireless patches along with it.
