Hi Werner,

I've got a test program that just displays the info with the DSPLY
op-code... It either requires V5R1 or V5R2, I don't remember which. I
hope that's not a problem. I'll include the source at the bottom of this
message.

Not my work, but Carsten Flensburg's work... but yes, I think it could be
useful. If nothing else, it lets you see whos using a file in the IFS,
which would otherwise be hard to do.

* f_favail = number of available file serial numbers to users
* f_fsid = filesystem ID. This will be 4294967295 if it's

* f_flag = file system flags (see below)

* f_objlinkmax = maximum number of hard-links for objects

* f_dirlinkmax = maximum number of hard-links for directories

* Since f_basetype is null-terminated, you should read it
