This feature is unsupported at this time, is not yet fully functional, and may cause serious problems.It is the same thing, that comment has been there for several years and is not going to go away unless someone tries to use it in earnest. I don't think the actual code is as bad as that comment suggests. Realtime on Irix was used by lots of folks, its the linux specific parts which may be need a little help.
Hmm I probably wrote that comment ;-) At one point realtime had a bad habit of clobbering your superblock when IO went to the wrong device... but I fixed that a couple years ago. At one point realtime -was- working fine.
If you'd like to try it, and have any concerns, just give it a whirl on a disposable filesystem. Anything that goes wrong will be contained to that filesystem, so no real worries.
