From: Johannes Berg Date: Wed, 22 Apr 2015 18:25:20 +0000 (+0200) Subject: mac80211: clean up global debugfs statistics X-Git-Tag: firefly_0821_release~176^2~1587^2~97^2~44 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f1160434c7658af3f7b0926b88df49a66cb3c3e0;p=firefly-linux-kernel-4.4.55.git mac80211: clean up global debugfs statistics The debugfs statistics macros are pointlessly verbose, so change that macro to just have a single argument. While at it, remove the unused counters and rename rx_expand_skb_head2 to the better rx_expand_skb_head_defrag.
