What’s new in this release


vminfo lib: add the following items to the /proc/vmstat parser:

  • vm_pgalloc_dma32
  • vm_pgrefill_dma32
  • vm_pgscan_direct_dma32
  • vm_pgscan_kswapd_dma32
  • vm_pgsteal_dma32
  • vm_pgsteal_direct_dma
  • vm_pgsteal_direct_dma32

The DMA32 memory zone is only available on 64-bit linux (low ~4GBytes of memory).
This patch can slightly modify the value of the memory counters reported by check_memory.


Fix several warnings reported by Codacy and Codeclimate.
