From: Paul Jackson <[email protected]>
The code in kernel/cgroup.c attach_task() which skips the
attachment of a task to the group it is already in has to be
removed. Cpusets depends on reattaching a task to its current
cpuset, in order to trigger updating the cpus_allowed mask in the
task struct.
The dependency of cpusets on this is a hack, granted, but an
important one. It lets us avoid checking for a changed cpuset
'cpus' setting in critical scheduler code paths.
