	  If you say Y here you will be able to mount and use XFS filesystems

	  originally designed to provide deterministic data rates suitable

	  for media streaming applications, but is also useful as a generic

	  mechanism for ensuring data and metadata/log I/Os are completely

	  separated.  Regular file I/Os are isolated to a separate device

	  from all other requests, and this can be done quite transparently

	  to applications via the inherit-realtime directory inode flag.



	  This feature is unsupported at this time, is not yet fully

	  functional, and may cause serious problems.

	  See the xfs man page in section 5 for additional information.
