+Subject: [PATCH liburing] test/recvsend_bundle: enlarge recv buf-ring to 2 MiB
+ to avoid ENOBUFS on ppc64
+
+Sub-test (d) "bundling with full socket" pre-fills the peer until EAGAIN.
+On some architectures (like ppc64), once the tcp_w/rmem min is set to higher
+value, like 64k and with autotuning on, the sender can queue more than the
+1MiB before the receiver arms multishot recv. With a 1MiB provided-buffer
+pool (MSG_SIZE * RECV_BIDS, so 8192 * 128), the first recv runs out of
+provided buffers and fails with -105 (ENOBUFS).
+
+Bump RECV_BIDS from 8192 to 16384, so the pool no longer underflows
+during the prefill on ppc64. This is a minimal, test-only tweak to
+stabilize results across different arches without changing test logic.
+
