Cover letter [PATCH net-next 0/2] Further robustify putting BPF progs

This series addresses a potential issue reported to us by Jann Horn with regards to putting progs. First patch moves progs generally under RCU destruction and second patch refactors getting of progs to simplify code a bit. For details, please see individual patches. Note, we think that addressing this one in net-next should be sufficient.

Thanks!
