Going to next bucket may not only\nskip the elements in current bucket silently, but also incur\nout-of-bound memory access or expose kernel memory to userspace if\ncurrent bucket_cnt is greater than bucket_size or zero.\n\nFixing it by stopping batch operation and returning -EBUSY when\nhtab_lock_bucket() fails, and the application can retry or skip the busy\nbatch as
