[pbs-devel] [PATCH v4 proxmox-backup 1/8] pbs api types: add garbage collection atime safety check flag

[Christian Ebner]

Add the `gc-atime-safety-check` flag to the datastore tuning
parameters. This flag allows to enable/disable a check to detect if
the atime update is honored by the filesystem backing the chunk store
during phase 1 of garbage collection and during datastore creation.

The default is to perform the check.
