[PATCHSET] xfs: kconfig and feature changes for 2025 LTS

["Darrick J. Wong" <djwong@kernel.org>]

Hi all,

Ahead of the 2025 LTS kernel, disable by default the two features that
we promised to turn off in September 2025: V4 filesystems, and the
long-broken ASCII case insensitive directories.

Since online fsck has not had any major issues in the 16 months since it
was merged upstream, let's also turn that on by default.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

This has been running on the djcloud for months with no problems.  Enjoy!
Comments and questions are, as always, welcome.
