There have been patches available for quite some time that implement this, but I'm not sure when they are likely to get into the mainline kernel. -Neil [1] http://lse.sourceforge.net/io/aio.html ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
