Inspired by these patches [1][2], this series aims to speed up the
initialization of hugetlb during the boot process through
parallelization.
It is particularly effective in large systems. On a machine equipped
with 1TB of memory and two NUMA nodes, the time for hugetlb
initialization was reduced from 2 seconds to 1 second.
Sorry to say, but why is that a scenario worth adding complexity for /
optimizing for? You don't cover that, so there is a clear lack in the
motivation.
2 vs. 1 second on a 1 TiB system is usually really just noise.
