This is a request to put XFS into the kernel, based on their large
database and small number of machines.  It doesn't cover the performance
of XFS, or the substantial work needed to merge XFS in to the mainline
Linux kernel.

The Linux release of XFS is just a single machine filesystem.  It is not
CXFS, or the high performance implementation of XFS that hooks into a
SAN or ST-over-HIPPI.

The SGI release of "Linux XFS" was a port of the Linux code to XFS, not
a XFS implementation for Linux.  The port was done in a way that
minimized the XFS changes, instead making substantial changes the Linux
kernel code.  While the IRIX FS interface does have good design
features, few people outside of SGI saw the benefit of having Linux be
an IRIX clone.
