[dpdk-dev] Unlinking hugepage backing file after initialiation

Hello,
As of DPDK2.1, backing files are created in hugetablefs during mapping (in eal_memory.c::rte_eal_hugepage_init()) and these files are not cleaned up (unlinked) after initialization (mmap-ing). This means, when the application crashes or stopped, the memory is still consumed. Therefore, is there any reason not to unlink backing files after initialization ? If no, I will send a patch for the change.
