mac80211: split sta_info_add
sta_info_add() has two functions: allocating a station info structure and inserting it into the hash table/list. Splitting these two functions allows allocating with GFP_KERNEL in many places instead of GFP_ATOMIC which is now required by the RCU protection. Additionally, in many places RCU protection is now no longer needed at all because between sta_info_alloc() and sta_info_insert() the caller owns the structure. This fixes a few race conditions with setting initial flags and similar, but not all (see comments in ieee80211_sta.c and cfg.c). More documentation on the existing races will be in a follow-up patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
