Is there an easy > way to find what are the new warnings? Yeah, scroll down, there is a diff of the old warnings vs new ones, and a summary of which files have changed their warning count: + 2 ../drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c + 3 ../drivers/net/wireless/intel/iwlwifi/mei/main.c - 1 ../drivers/net/wireless/intel/iwlwifi/mvm/ops.c + 2 ../drivers/net/wireless/intel/iwlwifi/mvm/ops.c - 2 ../drivers/net/wireless/microchip/wilc1000/wlan.c So presumably these are the warnings that were added: drivers/net/wireless/intel/iwlwifi/mei/main.c:193: warning: cannot understand function prototype: 'struct ' drivers/net/wireless/intel/iwlwifi/mei/main.c:1784: warning: Function parameter or member 'cldev' not described in 'iwl_mei_probe' drivers/net/wireless/intel/iwlwifi/mei/main.c:1784: warning: Function parameter or member 'id' not described in 'iwl_mei_probe' drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:3911:28: warning: incorrect type in assignment (different base types) drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:3911:28: expected restricted __le32 [assigned] [usertype] period_msec drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:3911:28: got restricted __le16 [usertype] drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:3913:30: warning: incorrect type in assignment (different base types) drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:3913:30: expected unsigned char [assigned] [usertype] keep_alive_id drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:3913:30: got restricted __le16 [usertype] drivers/net/wireless/intel/iwlwifi/mvm/ops.c:684:12: warning: context imbalance in 'iwl_mvm_start_get_nvm' - wrong count at exit > But in the big picture are you saying the net trees now have a rule that > no new W=1 and C=1 warnings are allowed?

For the code we merge directly we try to make sure there are no new warnings. I realize it's quite a bit of work for larger trees unless you have the infra so not a hard requirement (for you). FWIW the build bot we wrote is available on GH: https://github.com/kuba-moo/nipa But it currently hard codes tree matching logic for bpf and netdev, so would probably take a few hours to adopt it.
