[realtime code]

With regards to realtime code, the reason I was a bit reluctant is the
help entry for the realtime subvolume switch in the kernel config, which
says:

          This feature is unsupported at this time, is not yet fully
          functional, and may cause serious problems.

But maybe "realtime subvolume" is not the same thing as "using the
realtime block allocator?".


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.
