Maybe not a desktop question, but do you know btrfs's change
attribute/i_version status? Does it default to bumping i_version on
each change, or does that still need to be opted in? And has anyone
measured the performance delta (i_version vs. noi_version) recently?
Yeah it defaults to bumping it all the time, we just use the normal inode
changing infrastructure so it gets updated the same way everybody else does.
AFAIK there's no way to opt out of it, unless there's a -o noiversion that
exists? Thanks,
