Benoît, All,
On 2015-08-28 13:12 +0200, Benoît Thébaudeau spake thusly:
> The sparse_super feature is more efficient in terms of speed and
> available space, so set it by default if supported, i.e. for revision 1.
>
> This gives a huge speed gain for large resize2fs operations, especially
> for expansion.
