/* Description: The cacheflush_check() syscall */
/* Tests EINVAL error of cacheflush system call. */
/* Its expected behaviour is cacheflush() should return -EINVAL */
/* when cache parameter is not one of ICACHE, DCACHE, or BCACHE. */
/* */
/* Usage: <for command-line> */
/* cacheflush01 [-c n] [-e][-i n] [-I x] [-p x] [-t] */
/* where, -c n : Run n copies concurrently. */
/* -e : Turn on errno logging. */
/* -i n : Execute test n times. */
/* -I x : Execute test for x seconds. */
/* -P x : Pause for x seconds between iterations. */
/* -t : Turn on syscall timing. */
/* */
/* Total Tests: 1 */
