Comment 9 for bug 2025339

> So if we disable this by default, I think it should only impact performances of generated filesystems and probably not break anything else.

This sounds like it could be insignificant, or a major performance regression in some use cases. It's not clear which. Presumably orphan_file was introduced for a practical performance reason.

Please provide a proper analysis of the risk of performance regression here, and a documented reason why this cannot simply be worked around by adjusting how mke2fs is called (or by adjusting its configuration) in the use cases which require it, before proposing this fix for SRU.
