what is the status of GRIO support in the Linux port of XFS?
Also, if the answer is 'non existent', what is the recommended
alternative?  I've got an application that needs to stream a
huge amount of data to the harddrive without dropping any and
without blocking the sender.  We will be pushing the limits
of our high-end raid striped disks.  This seems the exactly
the type of thing GRIO was made for, but last I heard it was
missing from Linux XFS with no plans to add it.  Any change
in that?  I know I can get almost there with I/O priorities
and the RT features in 2.6... but its not quite the same
thing.
 
Apologies if this has been beat to death here or elsewhere...
I've googled the heck out of this and rummaged around in the
list archives (as much as this fscking corporate firewall will
let me) with little result.  I'll gladly RTFM if someone can
point me at the right one.  :-/

Feel free to CC me on replies, as I read the LKML in digest
format.

Thanks,
