Firing quorum before connection established can cause unexpected node to reboot. Assume there are 3 nodes in the cluster, Node 1, 2, 3. Node 2 and 3 have wrong ip address of Node 1 in cluster.conf and global heartbeat is enabled in the cluster. After the heatbeats are started on these three nodes, Node 1 will reboot due to quorum fencing. It is similar case if Node 1's networking is not ready when starting the global heartbeat. The reboot is not friendly as customer is not fully ready for ocfs2 to work. Fix it by not allowing firing quorum before the connection is established. In this case, ocfs2 will wait until the wrong configuration is fixed or networking is up to continue. Also update the log to guide the user where to check when connection is not built for a long time. Signed-off-by:

Reduce boilerplate code by using seq_open_private() instead of seq_open() Note that the code in and using sc_common_open() has been quite extensively changed. Not least because there was a latent memory leak in the code as was: if sc_common_open() failed, the previously allocated buffer was not freed. Signed-off-by:

Mel Gorman's commit 2457aec6 ("mm: non-atomically mark page accessed during page cache allocation where possible") removed mark_page_accessed() calls from NTFS without updating the matching find_lock_page() to find_get_page_flags(GFP_LOCK | FGP_ACCESSED) thus causing the page to never be marked accessed.

According to commit 80af2588 ("fanotify: groups can specify their f_flags for new fd"), file descriptors created as part of file access notification events inherit flags from the event_f_flags argument passed to syscall fanotify_init(2)[1]. Unfortunately O_CLOEXEC is currently silently ignored. Indeed, event_f_flags are only given to dentry_open(), which only seems to care about O_ACCMODE and O_PATH in do_dentry_open(), O_DIRECT in open_check_o_direct() and O_LARGEFILE in generic_file_open(). It's a pity, since, according to some lookup on various search engines and http://codesearch.debian.net/, there's already some userspace code which use O_CLOEXEC: - in systemd's readahead[2]: fanotify_fd = fanotify_init(FAN_CLOEXEC|FAN_NONBLOCK, O_RDONLY|O_LARGEFILE|O_CLOEXEC|O_NOATIME); - in clsync[3]: #define FANOTIFY_EVFLAGS (O_LARGEFILE|O_RDONLY|O_CLOEXEC) int fanotify_d = fanotify_init(FANOTIFY_FLAGS, FANOTIFY_EVFLAGS); - in examples [4] from "Filesystem monitoring in the Linux kernel" article[5] by Aleksander Morgado: if ((fanotify_fd = fanotify_init (FAN_CLOEXEC, O_RDONLY | O_CLOEXEC | O_LARGEFILE)) < 0) Additionally, since commit 48149e9d ("fanotify: check file flags passed in fanotify_init"). having O_CLOEXEC as part of fanotify_init() second argument is expressly allowed. So it seems expected to set close-on-exec flag on the file descriptors if userspace is allowed to request it with O_CLOEXEC. But Andrew Morton raised[6] the concern that enabling now close-on-exec might break existing applications which ask for O_CLOEXEC but expect the file descriptor to be inherited across exec(). In the other hand, as reported by Mihai Dontu[7] close-on-exec on the file descriptor returned as part of file access notify can break applications due to deadlock. So close-on-exec is needed for most applications. More, applications asking for close-on-exec are likely expecting it to be enabled, relying on O_CLOEXEC being effective. If not, it might weaken their security, as noted by Jan Kara[8]. So this patch replaces call to macro get_unused_fd() by a call to function get_unused_fd_flags() with event_f_flags value as argument. This way O_CLOEXEC flag in the second argument of fanotify_init(2) syscall is interpreted and close-on-exec get enabled when requested.

Pull networking updates from David Miller: "Most notable changes in here: 1) By far the biggest accomplishment, thanks to a large range of contributors, is the addition of multi-send for transmit. This is the result of discussions back in Chicago, and the hard work of several individuals. Now, when the ->ndo_start_xmit() method of a driver sees skb->xmit_more as true, it can choose to defer the doorbell telling the driver to start processing the new TX queue entires. skb->xmit_more means that the generic networking is guaranteed to call the driver immediately with another SKB to send. There is logic added to the qdisc layer to dequeue multiple packets at a time, and the handling mis-predicted offloads in software is now done with no locks held. Finally, pktgen is extended to have a "burst" parameter that can be used to test a multi-send implementation. Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4, virtio_net Adding support is almost trivial, so export more drivers to support this optimization soon. I want to thank, in no particular or implied order, Jesper Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann, David Tat, Hannes Frederic Sowa, and Rusty Russell. 2) PTP and timestamping support in bnx2x, from Michal Kalderon. 3) Allow adjusting the rx_copybreak threshold for a driver via ethtool, and add rx_copybreak support to enic driver. From Govindarajulu Varadarajan. 4) Significant enhancements to the generic PHY layer and the bcm7xxx driver in particular (EEE support, auto power down, etc.) from Florian Fainelli. 5) Allow raw buffers to be used for flow dissection, allowing drivers to determine the optimal "linear pull" size for devices that DMA into pools of pages. The objective is to get exactly the necessary amount of headers into the linear SKB area pre-pulled, but no more. The new interface drivers use is eth_get_headlen(). From WANG Cong, with driver conversions (several had their own by-hand duplicated implementations) by Alexander Duyck and Eric Dumazet. 6) Support checksumming more smoothly and efficiently for encapsulations, and add "foo over UDP" facility. From Tom Herbert. 7) Add Broadcom SF2 switch driver to DSA layer, from Florian Fainelli. 8) eBPF now can load programs via a system call and has an extensive testsuite. Alexei Starovoitov and Daniel Borkmann. 9) Major overhaul of the packet scheduler to use RCU in several major areas such as the classifiers and rate estimators. From John Fastabend. 10) Add driver for Intel FM10000 Ethernet Switch, from Alexander Duyck. 11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric Dumazet. 12) Add Datacenter TCP congestion control algorithm support, From Florian Westphal. 13) Reorganize sk_buff so that __copy_skb_header() is significantly faster.

Pull ARM SoC cleanups from Arnd Bergmann: "This time around, the cleanup branch contains mostly code removal. A number of board files for at91, imx and msm have become obsolete because of the DT conversion and are now ready to be removed.

Pull ARM SoC non-critical bug fixes from Arnd Bergmann: "These are bug fixes for harmless problems that were not important enough to get fixed in 3.17. The majority of these are OMAP specific, but there are also a couple for Marvell mvebu, cns3xxx, and others, as well as some updates for the MAINTAINERS file. In particular, Robert Jarzmik and Daniel Mack now volunteered to help out maintaining the PXA platform, Krzysztof Halasa took over the cns3xxx platform, Carlo Caione is the maintainer for the new Amlogic meson platform, and Matthias Brugger is now listed for the mediatek platform he recently contributed" * tag 'fixes-nc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (42 commits) MAINTAINERS: update Shawn's email address MAINTAINERS: condense some Tegra related entries MAINTAINERS: add Alexandre Courbot for Tegra MAINTAINERS: CNS3xxx and IXP4xx update.

The tx_desc struct holds 8 __be64 values. The original code in ring_tx_db() took a tx_desc pointer then casted it to an int pointer and then casted it to a u64 pointer. It was confusing and triggered some static checker warnings. I have changed the cxgb_pio_copy() function to only take tx_desc pointers. This isn't really a loss of flexibility because anything else was buggy to begin with. I also removed the casting on the destination pointer since that was unnecessary and a bit messy. Signed-off-by:

Christophe Leroy says: ==================== net: fs_enet: Remove non NAPI RX and add NAPI for TX When using a MPC8xx as a router, 'perf' shows a significant time spent in fs_enet_interrupt() and fs_enet_start_xmit(). 'perf annotate' shows that the time spent in fs_enet_start_xmit is indeed spent between spin_unlock_irqrestore() and the following instruction, hence in interrupt handling. This is due to the TX complete interrupt that fires after each transmitted packet. This patchset first remove all non NAPI handling as NAPI has become the only mode for RX, then adds NAPI for handling TX complete. This improves NAT TCP throughput by 21% on MPC885 with FEC.
