Due to a bug in my program, I initiated a read beyond eof. Specifically,
the file size is 13002 bytes and the read offset is 13312 (0x3400).
I would expect such a read to return 0 bytes read, but io_getevents returns -310, which is suspiciously equal to (13002 - 13312). I attach a reproducer. 4.2.5-201.fc22.x86_64 Are my expectations incorrect, or is this a bug in aio or xfs?
