[...] Ah - i have messed up my sched-devel.git script so the git-push went to kernel.org but into my home directory :-/ Should work now - let me know if it doesnt. i've also uploaded the patch series in quilt format, to: http://people.redhat.com/mingo/cfs-scheduler/devel/patches.tar.gz > [...] It can't be entirely explained with the Kernel Summit, as this > is not the first time patches appear out of the blue in form of a git > tree. i'm not sure what you mean, but i can definitely tell you that there was no scheduler hacking at the Kernel Summit. (there's no good wireless in the pubs and not enough space for a laptop anyway ;) The impressive linecount has been mostly achieved by dumb removal: sched: remove wait_runtime fields and features 4 files changed, 14 insertions(+), 161 deletions(-) sched: remove wait_runtime limit 5 files changed, 3 insertions(+), 124 deletions(-) sched: remove precise CPU load calculations #2 1 file changed, 1 insertion(+), 31 deletions(-) sched: remove precise CPU load 3 files changed, 9 insertions(+), 41 deletions(-) sched: remove stat_gran 4 files changed, 15 insertions(+), 50 deletions(-) Hack time to do them: ~10 minutes apiece. Removing stuff is _easy_ :-) The rest is finegrained, small changes. One of the harder patches was this one: commit 28c4b8ed35f0fc7050f186147da9e10b55e1e446 sched: introduce se->vruntime 3 files changed, 50 insertions(+), 33 deletions(-) And i sent you the first variant of that already: http://lkml.org/lkml/2007/9/2/76 we needed 2 days after the KS to put it into shape and send it out for feedback.
