ocfs2_readpages() use nonblocking flag to avoid page lock inversion. It will trigger cluster hang because that flag OCFS2_LOCK_UPCONVERT_FINISHING is not cleared if nonblocking lock cannot be granted at once. The flag would prevent dc thread from downconverting. So other nodes cannot acheive this lockres for ever. So we should not set OCFS2_LOCK_UPCONVERT_FINISHING when receiving ast if nonblocking lock had already returned. Signed-off-by:

Error handling if creation of root of debugfs in ocfs2_init() fails is broken. Although error code is set we fail to exit ocfs2_init() with error and thus initialization ends with success. Later when mounting a filesystem, ocfs2 debugfs entries end up being created in the root of debugfs filesystem which is confusing. Fix the error handling to bail out. Coverity id: 1227009.

Filesize is not a good indication that the file needs to be synced. An example where this breaks is: 1. Open the file in O_SYNC|O_RDWR 2. Read a small portion of the file (say 64 bytes) 3. Lseek to starting of the file 4. Write 64 bytes If the node crashes, it is not written out to disk because this was not committed in the journal and the other node which reads the file after recovery reads stale data (even if the write on the other node was successful) Signed-off-by:

Set nn_persistent_error to -ENOTCONN will stop reconnect since the "stop" condition in o2net_start_connect() will be true. stop = (nn->nn_sc || (nn->nn_persistent_error && (nn->nn_persistent_error != -ENOTCONN || timeout == 0))); This will make connection never be established if the first connection request is lost. Set nn_persistent_error to 0 when connect expired to fix this. With this changes, dlm will not be waken up when connect expired, this is OK since dlm depends on network, dlm can do nothing in this case if waken up. Let it wait there for network recover and connect built again to continue.

Node A sends master query request to node B which is the master. At this time lockres happens to be on purgelist. dlm_master_request_handler gets the dlm spinlock, finds the resource and releases the dlm spin lock. Right at this dlm_thread on this node could purge the lockres. dlm_master_request_handler can then acquire lockres spinlock and reply to Node A that node B is the master even though lockres on node B is purged. The above scenario will now make node A falsely think node B is the master which is inconsistent. Further if another node C tries to master the same resource, every node will respond they are not the master. Node C then masters the resource and sends assert master to all nodes. This will now make node A crash with the following message. dlm_assert_master_handler:1831 ERROR: DIE! Mastery assert from 9, but current owner is 10! Signed-off-by:

'args' are always set for ocfs2_read_locked_inode() and brelse() checks whether bh is NULL. So the test (args && bh) is unnecessary (plus the args part is really confusing anyway). Remove it. Coverity id: 1128856. Signed-off-by:

ocfs2_get_xattr_nolock() checks whether inode has any extended attributes (OCFS2_HAS_XATTR_FL). If not, it just sets 'ret' to -ENODATA but continues with checking inline and external attributes anyway (which is pointless although it does not harm). Just return immediately when we know there are no extended attributes in the inode. Coverity id: 1226906. Signed-off-by:

The change from \d+ to .+ inside __aligned() means that the following structure: struct test { u8 a __aligned(2); u8 b __aligned(2); }; essentially gets modified to struct test { u8 a; }; for purposes of kernel-doc, thus dropping a struct member, which in turns causes warnings and invalid kernel-doc generation. Fix this by replacing the catch-all (".") with anything that's not a semicolon ("[^;]").

dma_debug_init() is called by architecture specific code at different levels, but typically as a fs_initcall due to the debugfs initialization. Some platforms may have early callers of the DMA-API, running prior to the fs_initcall() level, which is not much of an issue unless CONFIG_DMA_API_DEBUG is set. When the DMA-API debugging facilities are turned on a caller will go through: debug_dma_map_{single,page} -> dma_mapping_error (inline function usually) -> debug_dma_mapping_error -> get_hash_bucket Calling get_hash_bucket() returns a valid hash value since we hash on high bits of the dma_addr cookie, but we will grab an unitialized spinlock, which typically won't crash but produce a warning, the real crash will however happen during the bucket list traversal because the list has not been initialized yet. An obvious solution is of course to move some of the offenders to run after the fs_initcall level, but since this might not always be an option, we add a flag "dma_debug_initialized" which is set to false by default, and set to true once dma_debug_init() has had a chance to run. The dma_debug_disabled() helper function previously introduced just needs to check for dma_debug_initialized to allow the caller to proceed or not.

high_memory isn't direct mapped memory so retrieving it's physical address isn't appropriate. But, it would be useful to check physical address of highmem boundary so it's justfiable to get physical address from it. In x86, there is a validation check if CONFIG_DEBUG_VIRTUAL and it triggers following boot failure reported by Ingo. ... BUG: Int 6: CR2 00f06f53 ...

Pull irq domain updates from Thomas Gleixner: "The real interesting irq updates: - Support for hierarchical irq domains: For complex interrupt routing scenarios where more than one interrupt related chip is involved we had no proper representation in the generic interrupt infrastructure so far. That made people implement rather ugly constructs in their nested irq chip implementations. The main offenders are x86 and arm/gic. To distangle that mess we have now hierarchical irqdomains which seperate the various interrupt chips and connect them via the hierarchical domains. That keeps the domain specific details internal to the particular hierarchy level and removes the criss/cross referencing of chip internals. The resulting hierarchy for a complex x86 system will look like this: vector mapped: 74 msi-0 mapped: 2 dmar-ir-1 mapped: 69 ioapic-1 mapped: 4 ioapic-0 mapped: 20 pci-msi-2 mapped: 45 dmar-ir-0 mapped: 3 ioapic-2 mapped: 1 pci-msi-1 mapped: 2 htirq mapped: 0 Neither ioapic nor pci-msi know about the dmar interrupt remapping between themself and the vector domain. If interrupt remapping is disabled ioapic and pci-msi become direct childs of the vector domain. In hindsight we should have done that years ago, but in hindsight we always know better :) - Support for generic MSI interrupt domain handling We have more and more non PCI related MSI interrupts, so providing a generic infrastructure for this is better than having all affected architectures implementing their own private hacks. - Support for PCI-MSI interrupt domain handling, based on the generic MSI support. This part carries the pci/msi branch from Bjorn Helgaas pci tree to avoid a massive conflict. The PCI/MSI parts are acked by Bjorn. I have two more branches on top of this.

Pull scheduler updates from Ingo Molnar: "The main changes in this cycle are: - 'Nested Sleep Debugging', activated when CONFIG_DEBUG_ATOMIC_SLEEP=y. This instruments might_sleep() checks to catch places that nest blocking primitives - such as mutex usage in a wait loop. Such bugs can result in hard to debug races/hangs. Another category of invalid nesting that this facility will detect is the calling of blocking functions from within schedule() -> sched_submit_work() -> blk_schedule_flush_plug(). There's some potential for false positives (if secondary blocking primitives themselves are not ready yet for this facility), but the kernel will warn once about such bugs per bootup, so the warning isn't much of a nuisance. This feature comes with a number of fixes, for problems uncovered with it, so no messages are expected normally. - Another round of sched/numa optimizations and refinements, for CONFIG_NUMA_BALANCING=y. - Another round of sched/dl fixes and refinements.

Pull ARM SoC/OMAP GPMC driver cleanup and move from Arnd Bergmann: "The GPMC driver has traditionally been considered a part of the OMAP platform code and tightly interweaved with some of the boards. With this cleanup, it has finally come to the point where it makes sense to move it out of arch/arm into drivers/memory, where we already have other drivers for similar hardware. The cleanups are still ongoing, with the goal of eventually having a standalone driver that does not require an interface to architecture code. This is a separate branch because of dependencies on multiple other branches, and to keep the drivers changes separate from the normal cleanups" * tag 'omap-gpmc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: memory: gpmc: Move omap gpmc code to live under drivers ARM: OMAP2+: Move GPMC initcall to devices.c ARM: OMAP2+: Prepare to move GPMC to drivers by platform data header ARM: OMAP2+: Remove unnecesary include in GPMC driver ARM: OMAP2+: Drop board file for 3430sdp ARM: OMAP2+: Drop board file for ti8168evm ARM: OMAP2+: Drop legacy code for gpmc-smc91x.c ARM: OMAP2+: Require proper GPMC timings for devices ARM: OMAP2+: Show bootloader GPMC timings to allow configuring the .dts file ARM: OMAP2+: Fix support for multiple devices on a GPMC chip select ARM: OMAP2+: gpmc: Sanity check GPMC fck on probe ARM: OMAP2+: gpmc: Keep Chip Select disabled while configuring it ARM: OMAP2+: gpmc: Always enable A26-A11 for non NAND devices ARM: OMAP2+: gpmc: Error out if timings fail in gpmc_probe_generic_child() ARM: OMAP2+: gpmc: Print error message in set_gpmc_timing_reg()

Pull ARM SoC DT updates from Arnd Bergmann: "The DT branch adds a lot of new stuff for additional SoC and board support. The branch is the largest one and contains 513 out of the total 972 non-merge arm-soc changesets for 3.19. Most of the changes are about enabling additional on-chip devices for existing machines, but there are also an unusual number of new SoC types being added this time: - AMLogic Meson8 - ARM Realview in DT mode - Allwinner A80 - Broadcom BCM47081 - Broadcom Cygnus - Freescale LS1021A - Freescale Vybrid 500 series - Mediatek MT6592, MT8127, MT8135 - STMicroelectronics STiH410 - Samsung Exynos4415 The level of support for the above differs widely, some are just stubs with nothing more than CPU, memory and a UART, but others are fairly complete. As usual, these get extended over time. There are also many new boards getting added, this is the list of model strings that are showing up in new dts files: - ARM RealView PB1176 - Altera SOCFPGA Arria 10 - Asus RT-N18U (BCM47081) - Buffalo WZR-1750DHP (BCM4708) - Buffalo WZR-600DHP2 (BCM47081) - Cygnus Enterprise Phone (BCM911360_ENTPHN) - D-Link DIR-665 - Google Spring - IGEP COM MODULE Rev.

Pull ARM SoC cleanups from Arnd Bergmann: "The remaining cleanups for 3.19 are to a large part result of devicetree conversion nearing completion on two other platforms besides AT91: - Like AT91, Renesas shmobile is in the process to migrate to DT and multiplatform, but using a different approach of doing it one SoC at a time. For 3.19, the r8a7791 platform and associated "Koelsch" board are considered complete and we remove the non-DT non-multiplatform support for this. - The ARM Versatile Express has supported DT and multiplatform for a long time, but we have still kept the legacy board files around, because not all drivers were fully working before. We have finally taken the last step to remove the board files. Other changes in this branch are preparation for the later branches or just unrelated to the more interesting changes: - The dts files for arm64 get moved into per-vendor directories for a clearer structure. - Some dead code removal (zynq, exynos, davinci, imx) - Using pr_*() macros more consistently instead of printk(KERN_*) in some platform code" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (71 commits) ARM: zynq: Remove secondary_startup() declaration from header ARM: vexpress: Enable regulator framework when MMCI is in use ARM: vexpress: Remove non-DT code ARM: imx: Remove unneeded .map_io initialization ARM: dts: imx6qdl-sabresd: Fix the microphone route ARM: imx: refactor mxc_iomux_mode() ARM: imx: simplify clk_pllv3_prepare() ARM: imx6q: drop unnecessary semicolon ARM: imx: clean up machine mxc_arch_reset_init_dt reset init ARM: dts: imx6qdl-rex: Remove unneeded 'fsl,mode' property ARM: dts: imx6qdl-gw5x: Remove unneeded 'fsl,mode' property ARM: dts: imx6qdl-sabresd: Use IMX6QDL_CLK_CKO define ARM: at91: remove useless init_time for DT-only SoCs ARM: davinci: Remove redundant casts ARM: davinci: Use standard logging styles ARM: shmobile: r8a7779: Spelling/grammar s/entity/identity/, s/map/mapping/ ARM: shmobile: sh7372: Spelling/grammar s/entity map/identity mapping/ ARM: shmobile: sh73a0: Spelling/grammar s/entity map/identity mapping/ ARM: EXYNOS: Remove unused static iomapping ARM: at91: fix build breakage due to legacy board removals ... -

Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann: "On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer. All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle.
