* sched/Documentation: Update sched-design-CFS.txt documentationLi Bin2013-09-121-3/+1
| | | | | | | | | | | | | | 2bd2d6f2dc ("sched: Replace use of entity_key()") had remove the entity_key() which function is to subtract a tasks vruntime by its groups minvruntime as the rbtree key. The phrase "there is a subtraction using rq->cfs.min_vruntime to account for possible wraparounds" in documentation feels strange and meaningless. So remove it.

* Documentation: update cgroupfs mount pointJörg Sommer2011-06-161-3/+4
| | | | | | | | | | | According to commit 676db4af0430 ("cgroupfs: create /sys/fs/cgroup to mount cgroupfs on") the canonical mountpoint for the cgroup filesystem is /sys/fs/cgroup. Hence, this should be used in the documentation.

* user namespaces: document CFS behaviorSerge E. Hallyn2008-12-081-0/+21
| | | | | | | | | | | | | Documented the currently bogus state of support for CFS user groups with user namespaces. In particular, all users in a user namespace should be children of the user which created the user namespace. This is yet to be implemented. Signed-off-by: Serge E.

* CFS scheduler: documentation about scheduling policiesMartin Steigerwald2008-09-231-2/+26
| | | | | | | | | | | | | The documentation about the CFS scheduler is scarse when it comes to scheduling policies. This patch adds a chapter about the scheduling policies it supports. Peter Zijlstra provided most of the information for it in http://marc.info/?l=linux-kernel&m=122210038326356&w=2 Signed-off-by: Martin Steigerwald <ms@teamix.de> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* Documentation: create new scheduler/ subdirectoryJ. Bruce Fields2008-02-071-0/+186
The top-level Documentation/ directory is unmanageably large, so we should take any obvious opportunities to move stuff into subdirectories. These sched-*.txt files seem an obvious easy case.
