Hi everyone,

I just want to clarify current status of these patches.
As I understand, moving to the new build system (for example,
meson+ninja as proposed[1] by Bruce) is a very long process.
But we have issues with imbalanced memory allocation now, and
IMHO it's better to fix them in a near future.

Latest version (v5) of balanced allocation patches adds linbuma
as general unconditional dependency which conflicts with the
current DPDK policies.

So, there are 2 option:

	1. Return back config option RTE_LIBRTE_EAL_NUMA_AWARE_HUGEPAGES
	   from the first version of the patch and disable it by default.

	2. Keep patch as it is now and make everyone install libnuma
	   for successful build.

I have no preferences about above options. I'm asking your opinions.

Bruce, Sergio, Thomas, what do you think?

Best regards, Ilya Maximets.

I would be ok with having libnuma as a dependency, so I think I'd prefer
option 2 to 1, assuming libnuma is available in all major Linux distros.
