After the syscall is made successfully the data should make it to disk eventually baring any other storage subsystem errors.

I believe this page provides the details necessary to understand/control about when that happens: http://www.westnet.com/~gsmith/content/linux-pdflush.htm

pdflush got replaced with per-BDI writeback since 2.6.32 http://kernelnewbies.org/Linux_2_6_32#head-72c3f91947738f1ea...

So it has. From what I can find though it appears the tunables and behaviour around the tunables is pretty much the same between flush and pdflush.
