Subject: [RFC PATCH 0/6] cpu-timers patches
Date: Wed,  9 Dec 2009 10:39:52 +0100
Message-Id: <1260351598-4203-1-git-send-email-sgruszka@redhat.com>

Here are patches for cpu-timers I mainly wrote to not call 
thread_group_cputime() in fastpath_timer_check(), which we
discuss in this thread:

http://thread.gmane.org/gmane.linux.kernel/909349/focus=912327
  
On the way I fix some other bugs (SIGEV_NONE timer, old increase value
in timer_settime()) and do other cleanups and optimizations, patch 3
however increase time when sighand->siglock is held. 

0001-cpu-timers-simplify-RLIMIT_CPU-handling.patch
0002-cpu-timers-cleanup-arm_timer.patch
0003-cpu-timers-return-true-old-increase-value-in-timer_.patch
0004-cpu-timers-change-SIGEV_NONE-timer-handling.patch
0005-cpu-timer-change-arm_timer-locking.patch
0006-cpu-timers-optimize-run_posix_cpu_timers.patch

Cheers
