From: Jeff Moyer on 30 Apr 2010 17:00 Hi, It was reported[1] that 32 bit readv and writev AIO operations were not functioning properly. It turns out that the code to convert the 32bit io vectors to 64 bits was never written. The results of that can be pretty bad, but in my testing, it mostly ended up in generating EFAULT as we walked off the list of I/O vectors provided. This patch set fixes the problem in my environment. Comments, as always, are greatly appreciated.
