I'm not seeing either of those warnings - I'm wondering if gcc recently got better about stack usage when inlining. also not seeing any reason why bch2_remap_range's stack frame should be that big, to my eye it looks like it should be more like 1k, so if anyone knows some magic for seeing stack frame layout that would be handy... anyways, there's a patch in my testing branch that should fix bch2_check_alloc_info
