Andrew,
The cpu group scheduler is ready and waiting for the container patches
in 2.6.23 :)
Here are some options with us:
a. (As Paul says) merge enough of container patches to enable
its use with cfs group scheduler (and possibly cpusets?)
b. Enable group scheduling bits in 2.6.23 using the user-id grouping
mechanism (aka fair user scheduler). For 2.6.24, we could remove
this interface and use Paul's container patches instead. Since this
means change of API interface between 2.6.23 and 2.6.24, I don't
prefer this option.
c. Enable group scheduling bits only in -mm for now (2.6.23-mmX), using
Paul's container patches. I can send you a short patch that hooks up
cfs group scheduler with Paul's container infrastructure.
If a. is not possible, I would prefer c.
Let me know your thoughts ..
