Dear Maintainer, Comparing /boot/config-* across recent backports (trixie) kernels: linux-image-7.1.3+deb13-amd64: CONFIG_NTFS3_FS=m (modern driver present) linux-image-7.1.7+deb13-amd64: CONFIG_NTFS3_FS not set, CONFIG_NTFS_FS=m instead linux-image-7.1.8+deb13-amd64: same as 7.1.7 This looks like a regression: the modern ntfs3 driver (read/write, actively maintained, enabled after the fix for #998627/#1000697) was replaced by the legacy ntfs.ko driver (largely unmaintained, limited write support) between 7.1.3 and 7.1.7/7.1.8. Effect: `mount -t ntfs3 ...` fails with "unknown filesystem type 'ntfs3'" and `modprobe ntfs3` fails with "Module ntfs3 not found", since the .ko is simply not built for these kernel versions. uname -r: 7.1.8+deb13-amd64
