Can you attach the iov_iter.s files from the broken build, plus the one with 'noinline' for comparison? Maybe something can be seen in there.I don't know how to extract the .s files easily from the AOSP build system, I'll look into that. I'm also now testing by downgrading to an older version of clang (10 instead of 11), to see if that matters at all or not...
Back from a day out - after it stopped raining. Trying to use up leave before the end of the year. Can you use objdump on the kernel binary itself and cut out the single function?
