We already have the ability to do user based classification which is tightened using PAM in userspace.

The removal of USER_SCHED will also simplify + the scheduler code with the removal of one major ifdef. There are also + issues USER_SCHED has with USER_NS. A decision was taken not to fix + those and instead remove USER_SCHED. Also new group scheduling + features will not be implemented for USER_SCHED. + +Who: Dhaval Giani <dhaval@xxxxxxxxxxxxxxxxxx> + +--------------------------- + What: PRISM54 When: 2.6.34 -- To unsubscribe from this list: send the line "unsubscribe linux-tip-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
