This is not my call actually. But beside comparing actual performance between AIO and sys_epoll, one of the advantages that the patch had is this :
arch/i386/kernel/entry.S | 4 drivers/char/Makefile | 4 fs/Makefile | 4 fs/file_table.c | 4 fs/pipe.c | 36 + include/asm-i386/poll.h | 1 include/asm-i386/unistd.h | 3 include/linux/fs.h | 4 include/linux/list.h | 5 include/linux/pipe_fs_i.h | 4 include/linux/sys.h | 2 include/net/sock.h | 10 net/ipv4/tcp.c | 4
That is, it has a very little "intrusion" in the original code by plugging in the existing architecture.
