Recent ARC commits added new statistic counters, such as iohits, uncached state, etc. Represent those. Also some of previously reported numbers were confusing or even made no sense. Those got some cleanup and restructuring.

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Performance enhancement (non-breaking change which improves efficiency)
  • Code cleanup (non-breaking change which makes code smaller or more readable)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Library ABI change (libzfs, libzfs_core, libnvpair, libuutil and libzfsbootenv)
  • Documentation (a change to man pages or other documentation)

This follows #14123 and #14243 , but refactors much more. Since the second PR is not merged yet, it is included here as first commit for now.

This also properly implements #14115 .
