I was super confused that you use prog_idx as a bit in jmp_table
and had to look into your tree what hid_bpf_jmp_table.c is doing.
Looks like it's not prog_id (which is prog->aux->id) that we know.
It's hid specific prog idx in that jmp table.
Maybe would be good to rename your prog_idx to something with 'hid' suffix or prefix?
or 'table' suffix or prefix ?
prog_table_idx ?

Other than that the patch set looking great.
I'm assuming removing call_hid_bpf_prog_put_deferred() and everything related
comes in the next set?
