"Linux sync Io:sync, Fsync and Fdatasync"Traditional UNIX implementations have a buffer cache or page cache in the kernel, and most disk I/O is buffered. When writing data to a file, the kernel usually copies the data into one of the buffers, and if the buffer is not yet full, it is not queued to the output queue, but waits for it to be full, or when the kernel needs to reuse the buffer to hold other disk block data, then the buffer is queued to the o
