RE: xfs_copy

[Murthy Kambhampaty <Murthy.Kambhampaty@goeci.com>]

The patches my Dave McCracken are the kernel code needed to support NGTP
(M:N threading). The userspace tools are available at the website my earlier
msg. pointed to. 

I suppose it is more accurate to say NGPT is >supported< in 2.4.19pre3 than
to say that it is "in"; at any rate IRIX-like threading facilities are
coming to linux soon. (Now I'm begginning to sound like I'm marketing NGPT,
sorry.)

If there is an interest in porting XFS code that relies on NGPT, I'd be
happy to be a tester (wish I could offer more, but my programming sills are
limited to high level languages for numerical/statistical analysis I'm
afraid).
