When checking if an autofs mount point is busy it isn't sufficient to only check if it's a mount point. For example, if the mount of an offset mountpoint in a tree is denied for this host by its export and the dentry becomes a process working directory the check incorrectly returns the mount as not in use at expire. This can happen since the default when mounting within a tree is nostrict, which means ingnore mount fails on mounts within the tree and continue. The nostrict option is meant to allow mounting in this case.

Pull 'full dynticks' support from Ingo Molnar: "This tree from Frederic Weisbecker adds a new, (exciting! :-) core kernel feature to the timer and scheduler subsystems: 'full dynticks', or CONFIG_NO_HZ_FULL=y. This feature extends the nohz variable-size timer tick feature from idle to busy CPUs (running at most one task) as well, potentially reducing the number of timer interrupts significantly. This feature got motivated by real-time folks and the -rt tree, but the general utility and motivation of full-dynticks runs wider than that: - HPC workloads get faster: CPUs running a single task should be able to utilize a maximum amount of CPU power. A periodic timer tick at HZ=1000 can cause a constant overhead of up to 1.0%. This feature removes that overhead - and speeds up the system by 0.5%-1.0% on typical distro configs even on modern systems. - Real-time workload latency reduction: CPUs running critical tasks should experience as little jitter as possible. The last remaining source of kernel-related jitter was the periodic timer tick. - A single task executing on a CPU is a pretty common situation, especially with an increasing number of cores/CPUs, so this feature helps desktop and mobile workloads as well. The cost of the feature is mainly related to increased timer reprogramming overhead when a CPU switches its tick period, and thus slightly longer to-idle and from-idle latency. Configuration-wise a third mode of operation is added to the existing two NOHZ kconfig modes: - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named as a config option. This is the traditional Linux periodic tick design: there's a HZ tick going on all the time, regardless of whether a CPU is idle or not. - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ=y], this turns off the periodic tick when a CPU enters idle mode. - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the tick when a CPU is idle, also slows the tick down to 1 Hz (one timer interrupt per second) when only a single task is running on a CPU. The .config behavior is compatible: existing !CONFIG_NO_HZ and CONFIG_NO_HZ=y settings get translated to the new values, without the user having to configure anything. CONFIG_NO_HZ_FULL is turned off by default. This feature is based on a lot of infrastructure work that has been steadily going upstream in the last 2-3 cycles: related RCU support and non-periodic cputime support in particular is upstream already. This tree adds the final pieces and activates the feature. The pull request is marked RFC because: - it's marked 64-bit only at the moment - the 32-bit support patch is small but did not get ready in time. - it has a number of fresh commits that came in after the merge window. The overwhelming majority of commits are from before the merge window, but still some aspects of the tree are fresh and so I marked it RFC. - it's a pretty wide-reaching feature with lots of effects - and while the components have been in testing for some time, the full combination is still not very widely used. That it's default-off should reduce its regression abilities and obviously there are no known regressions with CONFIG_NO_HZ_FULL=y enabled either. - the feature is not completely idempotent: there is no 100% equivalent replacement for a periodic scheduler/timer tick. In particular there's ongoing work to map out and reduce its effects on scheduler load-balancing and statistics. This should not impact correctness though, there are no known regressions related to this feature at this point. - it's a pretty ambitious feature that with time will likely be enabled by most Linux distros, and we'd like you to make input on its design/implementation, if you dislike some aspect we missed. Without flaming us to crisp! :-) Future plans: - there's ongoing work to reduce 1Hz to 0Hz, to essentially shut off the periodic tick altogether when there's a single busy task on a CPU. We'd first like 1 Hz to be exposed more widely before we go for the 0 Hz target though. - once we reach 0 Hz we can remove the periodic tick assumption from nr_running>=2 as well, by essentially interrupting busy tasks only as frequently as the sched_latency constraints require us to do - once every 4-40 msecs, depending on nr_running. I am personally leaning towards biting the bullet and doing this in v3.10, like the -rt tree this effort has been going on for too long - but the final word is up to you as usual.

A few formats previously had defective \n's o Remove unnecessary OOM messages as kmalloc() calls dump_stack o Coalesce formats to make grep easier, added missing spaces when coalescing formats o Use %s, __func__ instead of embedded function name o Removed unnecessary "cifs: " prefixes o Convert kzalloc with multiply to kcalloc o Remove unused cifswarn macro Signed-off-by: NJoe Perches <joe@perches.com> Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <smfrench@gmail.com>

Pull networking fixes from David Miller: 1) Several routines do not use netdev_features_t to hold such bitmasks, fixes from Patrick McHardy and Bjørn Mork. 2) Update cpsw IRQ software state and the actual HW irq enabling in the correct order. From Mugunthan V N. 3) When sending tipc packets to multiple bearers, we have to make copies of the SKB rather than just giving the original SKB directly. Fix from Gerlando Falauto. 4) Fix race with bridging topology change timer, from Stephen Hemminger. 5) Fix TCPv6 segmentation handling in GRE and VXLAN, from Pravin B Shelar. 6) Endian bug in USB pegasus driver, from Dan Carpenter. 7) Fix crashes on MTU reduction in USB asix driver, from Holger Eitzenberger. 8) Don't allow the kernel to BUG() just because the user puts some crap in an AF_PACKET mmap() ring descriptor. Fix from Daniel Borkmann. 9) Don't use variable sized arrays on the stack in xen-netback, from Wei Liu. 10) Fix stats reporting and an unbalanced napi_disable() in be2net driver. From Somnath Kotur and Ajit Khaparde. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (25 commits) cxgb4: fix error recovery when t4_fw_hello returns a positive value sky2: Fix crash on receiving VLAN frames packet: tpacket_v3: do not trigger bug() on wrong header status asix: fix BUG in receive path when lowering MTU net: qmi_wwan: Add Telewell TW-LTE 4G usbnet: pegasus: endian bug in write_mii_word() vxlan: Fix TCPv6 segmentation. gre: Fix GREv4 TCPv6 segmentation. bridge: fix race with topology change timer tipc: pskb_copy() buffers when sending on more than one bearer tipc: tipc_bcbearer_send(): simplify bearer selection tipc: cosmetic: clean up comments and break a long line drivers: net: cpsw: irq not disabled in cpsw isr in particular sequence xen-netback: better names for thresholds xen-netback: avoid allocating variable size array on stack xen-netback: remove redundent parameter in netbk_count_requests be2net: Fix to fail probe if MSI-X enable fails for a VF be2net: avoid napi_disable() when it has not been enabled be2net: Fix firmware download for Lancer be2net: Fix to receive Multicast Packets when Promiscuous mode is enabled on certain devices ...
