[pbs-devel] [PATCH v2 proxmox-backup 0/4] add GC cache stats and fix disabled state

[Christian Ebner]

Allows better fine-tuning of the garbage collection cache capacity by
providing the hit and miss count, as well as the hit ratio as output
to the garbage collection task log.

Further, fixes an issue with the cache not being disabled in case the
cache capacity was explicitly set to 0, by bypassing it altogether for
that case.

Changes since version 1 (thanks Lukas for feedback):
- Also display the cache hit ratio
- Fix the cache not being disabled when the capacity is set to 0,
  discovered while investigating the hit ratio for different
  capacities.
