+/* Description: bdflush() starts, flushes, or tunes the buffer-dirty-flush */
+/* daemon. Only a privileged process (one with the CAP_SYS_ADMIN */
+/* capability) may call bdflush(). */
+/* */
+/* If func is negative or 0, and no daemon has been started, */
+/* then bdflush() enters the daemon code and never returns. */
+/* */
+/* If func is 1, some dirty buffers are written to disk. */
+/* If func is 2 or more and is even (low bit is 0), then address */
+/* is the address of a long word, and the tuning parameter */
+/* numbered (func-2)/2 is returned to the caller in that address.*/
+/* */
+/* If func is 3 or more and is odd (low bit is 1), then data is */
+/* a long word, and the kernel sets tuning parameter numbered */
+/* (func-3)/2 to that value. */
+/* */
+/* The set of parameters, their values, and their legal ranges */
+/* are defined in the kernel source file fs/buffer.c. */
+/* */
+/* Return Value: */
+/* If func is negative or 0 and the daemon successfully starts, */
+/* bdflush() never returns. Otherwise, the return value is 0 on */
+/* success and -1 on failure, with errno set to indicate the */
