In short, file system filter are kernel modules. They intercept every
request being processed by XFS.
Good news is, we are in the process of making it open :)

We are building an Archive Appliance that generates sparse files.
Data written to filesystem is migrated to optical disks (UDO).
Based on usage policy, the actual files on filesystem are replaced with
sparse files.
On access of the file (from filesystem clients), the filesystem filter
(for XFS) triggers events to restore the actual file from Optical
storage onto the filesystem.
this trigger sounds interesting. could you describe it a bit more?
thanks!

I am working on a data management subsystem, and would appreciate any
insight people could share about real world applications that generate
sparse files. Can anybody share information or pointers to
applications that generate (and benefit from) sparse files?
Thanks,
