Hello everyone, This patchset is an updated version of the preemptible RCU patchset that Paul McKenney had posted it in September earlier this year that can be found here --> http://lkml.org/lkml/2007/9/10/213 This patchset incorporates the review comments from Oleg Nesterov and Steven Rostedt. The testing report of the patchset is as follows: ==================================================================== Patch-stack: 2.6.23-rc3 + cpu-hotplug patches from http://lkml.org/lkml/2007/11/15/239 + Preempt-RCU patches. Test: RCU-Torture running parallelly with CPU-Hotplug operations. Duration: 24 hours. Architectures: x86,x86_64, ppc64. ==================================================================== Currently it is based against the latest linux-2.6-sched-devel.git Awaiting your feedback!
thanks Gautham, the patchset from you and Paul looks good to me and i've
applied it to sched-devel.git to get it tested and reviewed some more.
from the Nitpicking Police, there are a couple of minor style
problems/warnings with the code, you can see it via:
scripts/checkpatch.pl --file kernel/rcu*.c
nothing serious - RCU is still one of the cleanest subsystems in the
kernel:
errors lines of code errors/KLOC
kernel/rcuclassic.c 0 575 0
kernel/rcupdate.c 1 138 7.2
kernel/rcupreempt.c 0 953 0
kernel/rcupreempt_trace.c 0 330 0
kernel/rcutorture.c 8 995 8.0
the eventual goal would be to match:
scripts/checkpatch.pl --file kernel/sched*.[ch]
output ;-)
