* High-resolution kernel timers
*
- * In contrast to the low-resolution timeout API implemented in
- * kernel/timer.c, hrtimers provide finer resolution and accuracy
- * depending on system configuration and capabilities.
- *
- * These timers are currently used for:
- * - itimers
- * - POSIX timers
- * - nanosleep
- * - precise in-kernel timing
+ * In contrast to the low-resolution timeout API, aka timer wheel,
+ * hrtimers provide finer resolution and accuracy depending on system
+ * configuration and capabilities.
*
* Started by: Thomas Gleixner and Ingo Molnar
*
* Credits:
- * based on kernel/timer.c
+ * Based on the original timer wheel code
*
* Help, testing, suggestions, bugfixes, improvements were
