[dpdk-dev] [PATCH 21.11 v2 0/3] eal: add memory pre-allocation from existing files

> Hugepage allocation from the system takes time, resulting in slow
> startup or sporadic delays later. Most of the time spent in kernel
> is zero-filling memory for security reasons, which may be irrelevant
> in a controlled environment. The bottleneck is memory access speed,
> so for speeduup the amount of memory cleared must be reduced.
> We propose a new EAL option --mem-file FILE1,FILE2,... to quickly
> allocate dirty pages from existing files and clean it as necessary.
> A new malloc_perf_autotest is provided to estimate the impact.
> More details are explained in relevant patches.
> 
> v2: fix CI failures
