Prasad Pandit 24687abf23 linux-aio: add IO_CMD_FDSYNC command support ... Libaio defines IO_CMD_FDSYNC command to sync all outstanding asynchronous I/O operations, by flushing out file data to the disk storage. Enable linux-aio to submit such aio request. When using aio=native without fdsync() support, QEMU creates pthreads, and destroying these pthreads results in TLB flushes. In a real-time guest environment, TLB flushes cause a latency spike. This patch helps to avoid such spikes.
