... which has nothing whatsoever on object lifetime rules. Could you
folks please document that somewhere? What pins what, what state
transitions are possible, etc.
BTW, the calling conventions for your foo_new() are annoying - instead of
"return -E... or 0, storing the reference to new object in var parameter
passed as the last argument", could you please just return ERR_PTR(-E...)
on error, a pointer to new object on success and to hell with those
struct foo **foo in the argument lists?
