       Having an odd phone problem with a Google Fi data only sim.  In the US if I go into aeroplane mode and then back again in a new area it takes a few minutes, finds a 2G network, tries to connect and then might take hours to finally connect to LTE.  If there's no 2G network, it never finds LTE and stays unconnected.  I can fix this by going into the 4636 phone information menu and setting the preferred network type to 'LTE only' instead of the default 'LTE/CDMA/EvDo/GSM/WCDMA (PRL)'.  Why is this?

       had fun with the eBPF selftests: even after I fixed the bug in the bpf key handling tidy up patches, the sefltetsts still wouldn't pass.  It turns out that BTF does not allow fully opaque structures in function prototypes (so the BPF load of the test  was failing because of this).  To fix the tests I had to add an empty struct bpf_key into one of the files the BTF generator saw ... saying this here just in case anyone else runs into the same obscure issue.
