Are some other configurations (or > compiler versions) where this code fails to build? (I'm a bit > surprised that it ever compiled!) The problem was introduced by 30686bf7f5b3 ("mac80211: convert HW flags to unsigned long bitmap"). The only LTS kernel which is missing the 68920c973254 ("net/mac80211/debugfs.c: prevent build failure with CONFIG_UBSAN=y") fix is the 4.4. The other don't have 30686bf7f5b3, e.g. 4.1, or have 30686bf7f5b3 and 68920c973254, e.g. 4.9. I've sent 68920c973254 to stable for inclusion into 4.4. https://www.spinics.net/lists/stable/msg209228.html Thanks, Daniel -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
