No, for that, I'm suggesting using a new bit in i_flags.
The "IS_PRIVATE()" thing is more a "if you know a-priori that you
aren't interested in pseudo-filesystems, you can already check that
bit, because it will be set for things like /proc and shmem mappings
and pipes etc".
Dmitry seemed to imply that the biggest use for the new bit was for
taking out whole pseudo-filesystems in one go. That would pretty much
be what S_PRIVATE is.
