xfsprogs current version is 5.14.2, latest version available is 6.4.0 It would be interesting to switch to a newer version as xfsprogs set big timestamps by default starting 5.15.0 (https://wiki.archlinux.org/title/XFS#Big_timestamps) This would allow to avoid the kernel warning: xfs filesystem being mounted at XYZ supports timestamps until 2038
xfsprogs has been bumped to version 6.4.0 in git by https://gitlab.com/buildroot.org/buildroot/-/commit/af48ddb139edded01530a76dd3a6c4bd2ae84775 and will be included in the 2023.11 release, thanks.
