Say you want to promptly duplicate what ever has been
writ to your disk on another disk, or remote drive or
cloud drive or whatever.

'inotify' and its kin can tell you what's changed,
but it's basically a POLLING sort of operation and
including an entire drive would be insanely slow.
It's a sort of localized rsync daemon.

Now SOMEWHERE Linux does put together a filename
and destination as it's about to write. The
big question is where, and can users SEE this ?

SoftRAID software does seem to tap into something
like this, so it's THERE, somewhere. I tried
looking at softRAID code but it's huge and only
just so well documented. No luck - I can't find
what it's looking at - kernel, driver, who knows ?
