What version of gcc are you using? 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
