Hi Josh, I ran into two more warnings with the two patches you sent me in private, using gcc-7.1.1:
lib/ubsan.o: warning: objtool: val_to_string.constprop.7()+0x97: leave instruction with modified stack frame .config: https://pastebin.com/dl/g04Dwdwx fs/fs_pin.o: warning: objtool: pin_kill()+0x139: stack state mismatch: cfa1=7+88 cfa2=7+96 .config: https://pastebin.com/dl/6gK6MadB I assume you are faster at analysing than me, so I have not tried to get to the bottom of these at all. Let me know if you need help reproducing the warnings. It's also possible that they are fixed by some other patches that you already sent but that are not in linux-next yet. Arnd
