mm: memcg: relayout structure mem_cgroup to avoid cache interference

2020-11-26T17:35:49Z

0day reported one -22.7% regression for will-it-scale page_fault2 case [1] on a 4 sockets 144 CPU platform, and bisected to it to be caused by Waiman's optimization (commit bd0b230fe1) of saving one 'struct page_counter' space for 'struct mem_cgroup'. Initially we thought it was due to the cache alignment change introduced by the patch, but further debug shows that it is due to some hot data members ('vmstats_local', 'vmstats_percpu', 'vmstats') sit in 2 adjacent cacheline (2N and 2N+1 cacheline), and when adjacent cache line prefetch is enabled, it triggers an "extended level" of cache false sharing for 2 adjacent cache lines. So exchange the 2 member blocks, while keeping mostly the original cache alignment, which can restore and even enhance the performance, and save 64 bytes of space for 'struct mem_cgroup' (from 2880 to 2816, with 0day's default RHEL-8.3 kernel config) [1]. https://lore.kernel.org/lkml/20201102091543.GM31092@shao2-debian/ Fixes: bd0b230fe145 ("mm/memcg: unify swap and memsw page counters") Reported-by: kernel test robot Signed-off-by: Feng Tang Acked-by: Waiman Long Signed-off-by: Linus Torvalds

firmware: xilinx: Use hash-table for api feature check

2020-11-24T14:13:54Z

Currently array of fix length PM_API_MAX is used to cache the pm_api version (valid or invalid). However ATF based PM APIs values are much higher then PM_API_MAX. So to include ATF based PM APIs also, use hash-table to store the pm_api version status.

net/packet: fix packet receive on L3 devices without visible hard header

2020-11-24T01:29:36Z

In the patchset merged by commit b9fcf0a0d826 ("Merge branch 'support-AF_PACKET-for-layer-3-devices'") L3 devices which did not have header_ops were given one for the purpose of protocol parsing on af_packet transmit path. That change made af_packet receive path regard these devices as having a visible L3 header and therefore aligned incoming skb->data to point to the skb's mac_header. Some devices, such as ipip, xfrmi, and others, do not reset their mac_header prior to ingress and therefore their incoming packets became malformed. Ideally these devices would reset their mac headers, or af_packet would be able to rely on dev->hard_header_len being 0 for such cases, but it seems this is not the case. Fix by changing af_packet RX ll visibility criteria to include the existence of a '.create()' header operation, which is used when creating a device hard header - via dev_hard_header() - by upper layers, and does not exist in these L3 devices. As this predicate may be useful in other situations, add it as a common dev_has_header() helper in netdevice.h.

Pull scheduler fixes from Thomas Gleixner: "A couple of scheduler fixes: - Make the conditional update of the overutilized state work correctly by caching the relevant flags state before overwriting them and checking them afterwards. - Fix a data race in the wakeup path which caused loadavg on ARM64 platforms to become a random number generator. - Fix the ordering of the iowaiter accounting operations so it can't be decremented before it is incremented. - Fix a bug in the deadline scheduler vs. priority inheritance when a non-deadline task A has inherited the parameters of a deadline task B and then blocks on a non-deadline task C. The second inheritance step used the static deadline parameters of task A, which are usually 0, instead of further propagating task B's parameters. The zero initialized parameters trigger a bug in the deadline scheduler" * tag 'sched-urgent-2020-11-22' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/deadline: Fix priority inheritance with multiple scheduling classes sched: Fix rq->nr_iowait ordering sched: Fix data-race in wakeup sched/fair: Fix overutilized update in enqueue_task_fair()
