cpuset, isolcpus: document relationship between cpusets & isolcpus

2015-03-19T18:28:20+00:00

Document the subtly changed relationship between cpusets and isolcpus. Turns out the old documentation did not match the code... Signed-off-by: Rik van Riel Suggested-by: Peter Zijlstra Acked-by: Zefan Li Signed-off-by: Tejun Heo

cpuset: PF_SPREAD_PAGE and PF_SPREAD_SLAB should be atomic flags

2014-09-25T02:16:06+00:00

When we change cpuset.memory_spread_{page,slab}, cpuset will flip PF_SPREAD_{PAGE,SLAB} bit of tsk->flags for each task in that cpuset. This should be done using atomic bitops, but currently we don't, which is broken. Tetsuo reported a hard-to-reproduce kernel crash on RHEL6, which happened when one thread tried to clear PF_USED_MATH while at the same time another thread tried to flip PF_SPREAD_PAGE/PF_SPREAD_SLAB. They both operate on the same task. Here's the full report: https://lkml.org/lkml/2014/9/19/230 To fix this, we make PF_SPREAD_PAGE and PF_SPREAD_SLAB atomic flags. v4: - updated mm/slab.c. (Fengguang Wu) - updated Documentation.

sched: Rename sched.c as sched/core.c in comments and Documentation

2013-06-19T10:58:42+00:00

Most of the stuff from kernel/sched.c was moved to kernel/sched/core.c long time back and the comments/Documentation never got updated. I figured it out when I was going through sched-domains.txt and so thought of fixing it globally. I haven't crossed check if the stuff that is referenced in sched/core.c by all these files is still present and hasn't changed as that wasn't the motive behind this patch.

cpuset: use N_MEMORY instead N_HIGH_MEMORY

2012-12-13T01:38:32+00:00

N_HIGH_MEMORY stands for the nodes that has normal or high memory. N_MEMORY stands for the nodes that has any memory. The code here need to handle with the nodes which have memory, we should use N_MEMORY instead.

Documentation: update cgroupfs mount point

2011-06-16T04:52:50+00:00

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. Signed-off-by: Jörg Sommer Acked-by: Paul Menage Signed-off-by: Randy Dunlap Signed-off-by: Linus Torvalds
