Changes for version 4.15 - 2012-04-10
- always include linux/types.h for fiemap, for compatibility to ancient systems (Paul Howarth).
- experimental support for IO::AIO::splice and ::tee (no aio_...).
- provide SEEK_HOLE and SEEK_DATA, if available.
- work around (again!) an immensely stupid bug in RHEL, defining autoconf macros in linux system headers (analysed by Paul Howarth).
- IO::AIO - Asynchronous Input/Output
