[dpdk-dev] [PATCH] test/eal_flags: Optimize memory flags test

[Phil Yang]

Since RTE_MAX_NUMA_NODES is configurable, the existing socket number
could greater than RTE_MAX_NUMA_NODES. Optimize test case to cover this
situation.(i.e RTE_MAX_NUMA_NODES=1)

Fixes: 45f1b6e8680a ('app: add new tests on eal flags')

Hi,

Your patch has been forgotten for months.
Do not hesitate to ping if no reply.

I have a question below.

Why the above change?

Hi Thomas,

That change just want to make sure below two buffers have enough space when configure RTE_MAX_NUMA_NODES=1.

/* construct an invalid socket mask with 2 megs on each socket plus
  * extra 2 megs on socket that doesn't exist on current system */
char invalid_socket_mem[SOCKET_MEM_STRLEN];
char buf[SOCKET_MEM_STRLEN];>   /* to avoid copying string onto itself */

Thanks,
Phil Yang
