are xfs handles persistent

[Martin Gasthuber <Martin.Gasthuber@xxxxxxx>]

Hi,

  in order to use xfs as a fast hierarchical namespace service (just 
the nameservice, no data) we need to have an external reference for an 
xfs file object. The '*_by_handle()' suite of functions seems to 
generate a unique handle for referencing xfs objects. Unclear is - are 
these handles persistent ??? i.e. retrieve handle - store it externally 
- dismount/mount filesystem - use external stored handle to access file 
(and attributes). Or did XFS provide other external unique references 
(magic inodes ;-)

thanxs in advance

  Martin
