sched: Add USER_SCHED to feature removal list
Peter Zijlstra suggested that we remove USER_SCHED at: http://lkml.org/lkml/2009/3/21/67 Removing USER_SCHED removes a lot of code from the scheduler and simplifies the code. We already have the ability to do user based classification which is tightened using PAM in userspace. Schedule USER_SCHED for removal in 2.6.34 Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Balbir Singh <balbir@in.ibm.com> Cc: Bharata B Rao <bharata@linux.vnet.ibm.com> Cc: Serge E.

9What: USER_SCHED
10When: 2.6.34
11
12Why: USER_SCHED was implemented as a proof of concept for group scheduling.
13 The effect of USER_SCHED can already be achieved from userspace with
14 the help of libcgroup. The removal of USER_SCHED will also simplify
15 the scheduler code with the removal of one major ifdef. There are also
16 issues USER_SCHED has with USER_NS. A decision was taken not to fix
17 those and instead remove USER_SCHED. Also new group scheduling
18 features will not be implemented for USER_SCHED.
