[PATCH 0/2] mac80211: hide tracepoint definition

[Omer El Idrissi]

This patch series does the following:
- Move static function that uses tracepoint from header file
  net/mac80211/driver-ops.h to net/mac80211/debugfs.c where it's called
- hides tracepoint definition flagged by UT=1 behind
  CONFIG_MAC80211_DEBUGFS

why? all the drv_ inlines are in driver-ops.h

first rule of commit text is to describe the problem you are tying to solve.

don't add unnecessary churn to the wireless code.

i moved it because multiple files include the header and when those are 
compiled they don't see the tracepoint definition because the next patch 
ifdef guards it under the same config that enables the only file the 
static function that uses the tracepoint is called from.

this static function was only used in that file and i didn't see any 
obvious reason for it's existance in that header so i moved it to the 
file where it's used.

commit messages are kept in the git history. should i send a v2 with a 
better commit message? or is the patch series problematic otherwise?

[PATCH 2/2] mac80211: hide drv_get_stats tracepoint with ifdef guard

[Omer El Idrissi]

Hide drv_get_stats tracepoint definition with CONFIG_MAC80211_DEBUGFS
which is the same config that enables net/mac80211/debugfs.c, where
the tracepoint is used in order to remove unused tracepoint warning
from UT=1.
