[PATCH 0/5] cputime: Generic virtual based cputime accounting v3

From: Frederic Weisbecker
Date: Sat Aug 04 2012 - 11:23:44 EST


Hi,

Changes since v2 (https://lwn.net/Articles/509575/) are only about
converting the "code domain tracking" naming to "context tracking"
as per Ingo's suggestion. And the result indeed looks much better.

git://github.com/fweisbec/linux-dynticks.git
vtime/generic-v3

Warning: this includes dependencies on rcu/idle and vtime
consolidation patchset.

Frederic Weisbecker (5):
context_tracking: New context tracking susbsystem
cputime: Don't allow virtual and irq finegrained cputime accounting
simultaneously
cputime: Allow dynamic switch between tick/virtual based cputime
accounting
cputime: Rename account_system_vtime to account_vtime
cputime: Generic on-demand virtual cputime accounting
