The patch titled
timer stats: updates
has been removed from the -mm tree. Its filename was
updated-debugging-feature-timer-stats-fixes.patch
This patch was dropped because it is obsolete
------------------------------------------------------
Subject: timer stats: updates
From: Ingo Molnar <mingo@elte.hu>
this is a major update to the /proc/timer_stats code and interface:
- change from linear list walking and global locking to a
scalable design: hash table and per-CPU locks for lookup,
global lock for adding new buckets (rare) and mutex for
serializing state changes with displaying stats.
- state transition simplification: active/inactive.
- dont auto-stop collection of events when displaying /proc/timer_stats
- include version information in /proc/timer_stats output
- include count of missed events (overflow count)
- sanitize start/stop time calculations
- change /proc/timer_stat from 0666 to 0644 ...
- fix bugs in milliseconds calculation and display
- fix division by zero bug
- add comments

* timer_stats is based on timer_top, a similar functionality which was part of
