[PATCH bpf-next v7 0/2] bpftool: Batch hash map dumps with bounded buffers

[Tianyi Chen <hi@tychen.cc>]

Rebased on current bpf-next, retaining Quentin's Acked-by.

Changes in v7:
- Use the upstream error formatter for batch failures.
- Refresh the matched-base timings and syscall counts in patch 1.

The 12 batch tests and both upstream non-iterable-map tests pass on
x86-64 KVM with Linux 7.2.13 and 7.3.0. All 33 focused subtests also pass
with the map-info/recursive series; per-CPU fallback output is unchanged.

v6: https://lore.kernel.org/r/20260925174412.2028749-1-hi@tychen.cc
