[pbs-devel] [PATCH proxmox-backup 0/5] add 'sync-level' to datatore tuning options

[Dominik Csapak]

this series is a successor to my previous RFC for it.[0]

changes from RFC:
* seperate introducing of the option and changing the default
* renaming to DatastoreFSyncLevel
* adding more and better comments + docs
* saving the whole level and not only a bool in the datastore/chunk_store
* adding a fsync on the dir handle for the 'file' case in insert_chunk
* split the change to 'replace_file' into seperate patch

the first patch is mostly unrelated, but it introduces a place where
we can document the option, and could be applied independent from
the remaining patches of this series.

the second patch only changes the use of replace_file in insert_chunk,
so that could also be applied independently.
