[LTP] [PATCH 8/9] doc: Document CPU and common test helpers

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

Fix the kernel-doc formatting in include/tst_common.h and include
both tst_common.h and tst_cpu.h in the C API reference documentation.

  * TST_RETRY_FUNC() - Repeatedly retry a function with an increasing delay.
- * @FUNC - The function which will be retried
- * @ECHCK - Function/macro for validating @FUNC return value
  *
- * This macro will call @FUNC in a loop with a delay between retries.
- * If ECHCK(ret) evaluates to non-zero, the loop ends. The delay between
- * retries starts at one microsecond and is then doubled each iteration until
- * it exceeds one second (the total time sleeping will be approximately one
- * second as well). When the delay exceeds one second, the loop will end.
- * The TST_RETRY_FUNC() macro returns the last value returned by @FUNC.
+ * @FUNC: The function which will be retried.
+ * @ECHCK: Function or macro for validating @FUNC return value.
+ *
+ * This macro will call @FUNC in a loop with an exponential delay between
+ * retries. If ECHCK(ret) evaluates to non-zero, the loop ends. The delay
+ * starts at one microsecond and doubles each iteration until it exceeds
+ * one second (scaled by tst_multiply_timeout()). When the maximum delay
+ * is exceeded, the loop ends.
+ *
+ * Return: The last value returned by @FUNC.
