[PATCH v3] app/procinfo: display eventdev xstats for PMD data

[Sevincer, Abdullah]

Got it. Looking at forums and made some reading, like you said it does not matter much.
I will keep consistency with other call methods so keep malloc.

I will push another patch removing extra line.

Thanks.

It doesn't matter much if you use malloc vs calloc.
But there are some static analysis tools that might look at calloc as way to determine number of elememts for later array checks.

Also, the kernel checkpatch warns when kmalloc is used but kcalloc or kmalloc_array could be used instead. That is Linux kernel specific but same idea applies.
