Is there a file system out there that supports custom file size limit ?

Hi,
I'm aware that EXT4 has a Code:max_dir_size_kb mount option to set up the max size of each directory. It doesn't have a similar option to specify the max size of individual files, though.
Is somebody aware of another file system that could do this ? I checked XFS, ZFS and ReiserFS, but didn't find anything, though I'm no expert on those file systems.
To be more specific about what I try to achieve : I'd like to limit the size of individual files that can be stored on a Samba share (individual files, not global quota, e.g. prevent users from storing files exceeding a given size). Samba doesn't have an option for this, and the Linux /etc/security/limits.conf doesn't work either with Samba (see https://askubuntu.com/questions/1315...4-ubuntu-20-04, and the answer below : the Samba developers explained that file size limits set up in /etc/security/limits.conf are not enforced).
So my idea was to define that limit on the file system level, but it doesn't appear there is a file system supporting this feature.
