Subject: [PATCH V2 0/2] sched: Cleanups,fixes in nohz_kick_needed()
Date: Wed, 30 Oct 2013 08:42:33 +0530 [thread overview]
Message-ID: <20131030031145.23426.22930.stgit@preeti.in.ibm.com> (raw)
Changes from V1:https://lkml.org/lkml/2013/10/21/248
1. Swapped the order of PATCH1 and PATCH2 in V1 so as to not mess with the
nr_busy_cpus parameter computation during asymmetric balancing, while fixing
it.
2. nohz_busy_cpus parameter is to be updated and queried at only one level of
the sched domain-sd_busy where it is relevant.
3. Introduce sd_asym to represent the sched domain where asymmetric load
balancing has to be done.
