Subject[patch 1/9] time: Remove useless filenames in top level comments
Remove the pointless filenames in the top level comments. They have no
value at all and just occupy space. While at it tidy up some of the
comments and remove a stale one.

* 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
