I noticed that the SGI XFS source code has been included in Severn's kernel source tree. Will XFS will be part of next official release of RedHat ?
XFS will certainly be in the 2.6 based releases, maybe in 2.4 based stuff, and may even make the base 2.4 kernel in time - most of the infrastructure is now present.
Whether we ship install support for it - I don't know.
