Re: F9 (bug?) Superblock features different from backup

["Ahmed Kamal" <email.ahmedkamal@xxxxxxxxxxxxxx>]

bingo, I had created a virtualbox VM, which created a 8G file, that must have triggered the superblock changes. I feel much calmer now. Thank you :)

sure, things like the first time a "large" (> 2G file) is written it
will set a flag to that effect.

Or the first time an extent-based file is created on ext4.

We've talked about removing these, actually, and requiring the flags to
be set at mkfs time, or via tune2fs, if you wish to use the feature,
rather than silently turning them on.
