 buggy
 disk cache/inode allocations by ntfs3 kernel module.

I'm posting there first time, so I through it like generic bug mailing list, but I can say, that, for example, version 6.12.50-lts a little less pron to bug, but it occurs there as well. I'm using Linux 6.16.10 for now. So, bug is present a while, but i hardly to tell, in what kernel version it appeared, cause earlier, I didn't manage that big amount of files. Again, it's okay with ntfs-3g.
