Hi,

first of all congratulations for finishing the initial first release.
Some questions, just out of curiosity:

Quoted 6 lines

* Fast recovery after a system crash or power outage

* Journaling for file system integrity

* Journaling of meta-data only

does this mean JSF/Linux always journals only the meta-data, or is that
an option?
Does it perform full data-journaling under AIX?

Quoted 8 lines

* Extent-based allocation

* Excellent overall performance

* 64 bit file system

* Built to scale. In memory and on-disk data structures are designed to scale beyond practical limit

Is this scaling only for size, or also for performance (many disks on
many controllers) like XFS (at least on SGI iron)?

Thanks
Martin
