So I finally (sorry) decided to apply this, but I get a few issues with
it (aside from trivial rebase issues). If you're not able to fix them
now let me know and I can:
1) Lots of places put the sinfo on the stack, but it's now way bigger,
so we get warnings like
net/mac80211/ethtool.c: In function ‘ieee80211_get_stats’:
net/mac80211/ethtool.c:204:1: warning: the frame size of 1752 bytes is larger than 1024 bytes [-Wframe-larger-than=]
net/mac80211/ethtool.c:74 ieee80211_get_stats() warn: 'sinfo' puts 1672 bytes on stack
I guess we need to pull those out to dynamic allocations.
net/mac80211/cfg.c:3762:12: warning: context imbalance in 'ieee80211_get_txq_stats' - different lock contexts for basic block
net/mac80211/tx.c: In function ‘ieee80211_txq_set_params’:
net/mac80211/tx.c:1478:1: warning: control reaches end of non-void function [-Wreturn-type]
also show up.
