Hi,
these three patches apply on top of Neeraj's v5 of his "A design for
future-proofing fsync() configuration". I'm sending this as a reply to
his v5 to keep the discussion in one place -- I think ultimately, we may
want to merge both series into a single one anyway. But please shout at
me if this is considered bad style and I'll split it out into a separate
thread.
In any case, these three patches implement fsyncing for loose and packed
references using the proposed `core.fsync` option, with three additional
knobs:
- "loose-ref" will fsync loose references.
- "packed-refs" will fsync packed references.
- "refs" will fsync all references, which should ideally also
include all new backends like the reftable backend.
I think this extension demonstrates that the design proposed by Neeraj
is quite easy to extend without too much boilerplate.
