Analyze and fix the following issue in the Linux kernel code: [PATCH] sched: RCU domains
Problem Details: One of the problems with the multilevel balance-on-fork/exec is that it needs to jump through hoops to satisfy sched-domain's locking semantics (that is, you may traverse your own domain when not preemptable, and you may traverse others' domains when holding their runqueue lock). balance-on-exec had t...

Analyze and fix the following issue in the Linux kernel code: [PATCH] sched: remove degenerate domains
Problem Details: Remove degenerate scheduler domains during the sched-domain init. For example on x86_64, we always have NUMA configured in. On Intel EM64T systems, top most sched domain will be of NUMA and with only one sched_group in it. With fork/exec balances(recent Nick's fixes in -mm tree), we always endup tak...

Analyze and fix the following issue in the Linux kernel code: [PATCH] sched: null domains
Problem Details: Fix the last 2 places that directly access a runqueue's sched-domain and assume it cannot be NULL. That allows the use of NULL for domain, instead of a dummy domain, to signify no balancing is to happen. No functional changes.

Analyze and fix the following issue in the Linux kernel code: [PATCH] sched: fix SMT scheduling problems
Problem Details: SMT balancing has a couple of problems. Firstly, active_load_balance is too complex - basically it should be a dumb helper for when the periodic balancer has determined there is an imbalance, but gets stuck because the task is running. So rip out all its "smarts", and just make it move one task to th...
