git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull RCU updates from Thomas Gleixner: "A large update to RCU: Preparatory work for consolidating the RCU flavors: - Introduce grace-period sequence numbers to the RCU-bh, RCU-preempt, and RCU-sched flavors, replacing the old ->gpnum and ->completed pair of fields. This change allows lockless code to obtain the complete grace-period state with a single READ_ONCE(), which is needed to maintain tolerable lock contention during the upcoming consolidation of the three RCU flavors. Note that grace-period sequence numbers are already used by rcu_barrier(), expedited RCU grace periods, and SRCU, and are thus already heavily used and well-tested. Joel Fernandes contributed a number of excellent fixes and improvements. - Clean up some grace-period-reporting loose ends, including improving the handling of quiescent states from offline CPUs and fixing some false-positive WARN_ON_ONCE() invocations. (Strictly speaking, the WARN_ON_ONCE() invocations were quite correct, but their invariants were (harmlessly) violated by the earlier sloppy handling of quiescent states from offline CPUs.) In addition, improve grace-period forward-progress guarantees so as to allow removal of fail-safe checks that required otherwise needless lock acquisitions. Finally, add more diagnostics to help debug the upcoming consolidation of the RCU-bh, RCU-preempt, and RCU-sched flavors.

2018-08-13f2fs: support fault_type mount optionChao Yu
Previously, once fault injection is on, by default, all kind of faults will be injected to f2fs, if we want to trigger single or specified combined type during the test, we need to configure sysfs entry, it will be a little inconvenient to integrate sysfs configuring into testsuit, such as xfstest. So this patch introduces a new mount option 'fault_type' to assist old option 'fault_injection', with these two mount options, we can specify any fault rate/type at mount-time.

As Dan Carpenter reported: The patch 20ee4382322c: "f2fs: issue small discard by LBA order" from Jul 8, 2018, leads to the following Smatch warning: fs/f2fs/segment.c:1277 __issue_discard_cmd_orderly() warn: 'dc' was already freed. See also: fs/f2fs/segment.c:2550 __issue_discard_cmd_range() warn: 'dc' was already freed.

2018-08-13f2fs: split discard command in prior to block layerChao Yu
Some devices has small max_{hw,}discard_sectors, so that in __blkdev_issue_discard(), one big size discard bio can be split into multiple small size discard bios, result in heavy load in IO scheduler and device, which can hang other sync IO for long time. Now, f2fs is trying to control discard commands more elaboratively, in order to make less conflict in between discard IO and user IO to enhance application's performance, so in this patch, we will split discard bio in f2fs in prior to in block layer to reduce issuing multiple discard bios in a short time.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-08-13 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add driver XDP support for veth. This can be used in conjunction with redirect of another XDP program e.g. sitting on NIC so the xdp_frame can be forwarded to the peer veth directly without modification, from Toshiaki. 2) Add a new BPF map type REUSEPORT_SOCKARRAY and prog type SK_REUSEPORT in order to provide more control and visibility on where a SO_REUSEPORT sk should be located, and the latter enables to directly select a sk from the bpf map. This also enables map-in-map for application migration use cases, from Martin. 3) Add a new BPF helper bpf_skb_ancestor_cgroup_id() that returns the id of cgroup v2 that is the ancestor of the cgroup associated with the skb at the ancestor_level, from Andrey. 4) Implement BPF fs map pretty-print support based on BTF data for regular hash table and LRU map, from Yonghong. 5) Decouple the ability to attach BTF for a map from the key and value pretty-printer in BPF fs, and enable further support of BTF for maps for percpu and LPM trie, from Daniel. 6) Implement a better BPF sample of using XDP's CPU redirect feature for load balancing SKB processing to remote CPU. The sample implements the same XDP load balancing as Suricata does which is symmetric hash based on IP and L4 protocol, from Jesper. 7) Revert adding NULL pointer check with WARN_ON_ONCE() in __xdp_return()'s critical path as it is ensured that the allocator is present, from Björn. ==================== Signed-off-by: David S.

2018-08-13net: Change the layout of structure trace_event_raw_fib_table_lookupZong Li
There is an unalignment access about the structure 'trace_event_raw_fib_table_lookup'. In include/trace/events/fib.h, there is a memory operation which casting the 'src' data member to a pointer, and then store a value to this pointer point to. p32 = (__be32 *) __entry->src; *p32 = flp->saddr; The offset of 'src' in structure trace_event_raw_fib_table_lookup is not four bytes alignment. On some architectures, they don't permit the unalignment access, it need to pay the price to handle this situation in exception handler. Adjust the layout of structure to avoid this case.
