[Qemu-devel] [PATCH RFC 0/3] error: allow local errors to trigger abort

[Michael S. Tsirkin]

    It's a common idiom:
    
        Error *local_err = NULL;
        ....
        foo(&local_err);
        ...
        if (local_err) {
            error_propagate(errp, local_err);
            return;
        }
    
    Unfortunately it means that call to foo(&local_err) will
    not abort even if errp is set to error_abort.
    
    Instead, we get an abort at error_propagate which is too late.
    
    To fix, add an API to check errp and set local_err to error_abort
    if errp is error_abort.
