git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs Pull xfs update from Dave Chinner: "This update contains: - RENAME_WHITEOUT support - conversion of per-cpu superblock accounting to use generic counters - new inode mmap lock so that we can lock page faults out of truncate, hole punch and other direct extent manipulation functions to avoid racing mmap writes from causing data corruption - rework of direct IO submission and completion to solve data corruption issue when running concurrent extending DIO writes. Also solves problem of running IO completion transactions in interrupt context during size extending AIO writes. - FALLOC_FL_INSERT_RANGE support for inserting holes into a file via direct extent manipulation to avoid needing to copy data within the file - attribute block header field overflow fix for 64k block size filesystems - Lots of changes to log messaging to be more informative and concise when errors occur. Also prevent a lot of unnecessary log spamming due to cascading failures in error conditions. - lots of cleanups and bug fixes One thing of note is the direct IO fixes that we merged last week after the window opened.

Pull MTD updates from Brian Norris: "Common MTD: - Add Kconfig option for keeping both the 'master' and 'partition' MTDs registered as devices. This would really make a better default if we could do it over, as it allows a lot more flexibility in (1) determining the flash topology of the system from user-space and (2) adding temporary partitions at runtime (ioctl(BLKPG)). Unfortunately, this would possibly cause user-space breakage, as it will cause renumbering of the /dev/mtdX devices. We'll see if we can change this in the future, as there have already been a few people looking for this feature, and I know others have just been working around our current limitations instead of fixing them this way. - Along with the previous change, add some additional information to sysfs, so user-space can read the offset of each partition within its master device SPI NOR: - add new device tree compatible binding to represent the mostly-compatible class of SPI NOR flash which can be detected by their extended JEDEC ID bytes, cutting down the duplication of our ID tables - misc. new IDs Various other miscellaneous fixes and changes" * tag 'for-linus-20150422' of git://git.infradead.org/linux-mtd: (53 commits) mtd: spi-nor: Add support for Macronix mx25u6435f serial flash mtd: spi-nor: Add support for Winbond w25q64dw serial flash mtd: spi-nor: add support for the Winbond W25X05 flash mtd: spi-nor: support en25s64 device mtd: m25p80: bind to "nor-jedec" ID, for auto-detection Documentation: devicetree: m25p80: add "nor-jedec" binding mtd: Make MTD tests cancelable mtd: mtd_oobtest: Fix bitflip_limit usage in test case 3 mtd: docg3: remove invalid __exit annotations mtd: fsl_ifc_nand: use msecs_to_jiffies for time conversion mtd: atmel_nand: don't map the ROM table if no pmecc table offset in DT mtd: atmel_nand: add a definition for the oob reserved bytes mtd: part: Remove partition overlap checks mtd: part: Add sysfs variable for offset of partition mtd: part: Create the master device node when partitioned mtd: ts5500_flash: Fix typo in MODULE_DESCRIPTION in ts5500_flash.c mtd: denali: Disable sub-page writes in Denali NAND driver mtd: pxa3xx_nand: cleanup wait_for_completion handling mtd: nand: gpmi: Check for scan_bbt() error mtd: nand: gpmi: fixup return type of wait_for_completion_timeout ...

2015-04-22crush: straw2 bucket type with an efficient 64-bit crush_ln()Ilya Dryomov1-2/+10
This is an improved straw bucket that correctly avoids any data movement between items A and B when neither A nor B's weights are changed. Said differently, if we adjust the weight of item C (including adding it anew or removing it completely), we will only see inputs move to or from C, never between other items in the bucket. Notably, there is not intermediate scaling factor that needs to be calculated. The mapping function is a simple function of the item weights. The below commits were squashed together into this one (mostly to avoid adding and then yanking a ~6000 lines worth of crush_ln_table): - crush: add a straw2 bucket type - crush: add crush_ln to calculate nature log efficently - crush: improve straw2 adjustment slightly - crush: change crush_ln to provide 32 more digits - crush: fix crush_get_bucket_item_weight and bucket destroy for straw2 - crush/mapper: fix divide-by-0 in straw2 (with div64_s64() for draw = ln / w and INT64_MIN -> S64_MIN - need to create a proper compat.h in ceph.git) Reflects ceph.git commits 242293c908e923d474910f2b8203fa3b41eb5a53, 32a1ead92efcd351822d22a5fc37d159c65c1338, 6289912418c4a3597a11778bcf29ed5415117ad9, 35fcb04e2945717cf5cfe150b9fa89cb3d2303a1, 6445d9ee7290938de1e4ee9563912a6ab6d8ee5f, b5921d55d16796e12d66ad2c4add7305f9ce2353.

2015-04-20smp: don't use 16-bit words for atomic accessesLinus Torvalds1-1/+1
Yes, it should work, but it's a bad idea. Not only did ARM64 not have the 16-bit access code (there's a separate patch to add it), it's just not a good atomic type. Some architectures fundamentally don't do atomic accesses in them (alpha), and it's not like it saves any space here anyway because of structure packing issues. We normally should aim for flags to be "unsigned int" or "unsigned long". And if space is at a premium, use a single byte (although that causes problems on alpha again). There might be very special cases where a 16-byte entity is really wanted, but this is not one of them. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2015-04-18Break up monolithic iommu table/lock into finer graularity pools and lockSowmini Varadhan1-0/+51
Investigation of multithreaded iperf experiments on an ethernet interface show the iommu->lock as the hottest lock identified by lockstat, with something of the order of 21M contentions out of 27M acquisitions, and an average wait time of 26 us for the lock. This is not efficient. A more scalable design is to follow the ppc model, where the iommu_map_table has multiple pools, each stretching over a segment of the map, and with a separate lock for each pool. This model allows for better parallelization of the iommu map search. This patch adds the iommu range alloc/free function infrastructure.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull usernamespace mount fixes from Eric Biederman: "Way back in October Andrey Vagin reported that umount(MNT_DETACH) could be used to defeat MNT_LOCKED. As I worked to fix this I discovered that combined with mount propagation and an appropriate selection of shared subtrees a reference to a directory on an unmounted filesystem is not necessary. That MNT_DETACH is allowed in user namespace in a form that can break MNT_LOCKED comes from my early misunderstanding what MNT_DETACH does. To avoid breaking existing userspace the conflict between MNT_DETACH and MNT_LOCKED is fixed by leaving mounts that are locked to their parents in the mount hash table until the last reference goes away. While investigating this issue I also found an issue with __detach_mounts. The code was unnecessarily and incorrectly triggering mount propagation. Resulting in too many mounts going away when a directory is deleted, and too many cpu cycles are burned while doing that. Looking some more I realized that __detach_mounts by only keeping mounts connected that were MNT_LOCKED it had the potential to still leak information so I tweaked the code to keep everything locked together that possibly could be. This code was almost ready last cycle but Al invented fs_pin which slightly simplifies this code but required rewrites and retesting, and I have not been in top form for a while so it took me a while to get all of that done. Similiarly this pull request is late because I have been feeling absolutely miserable all week.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.1 development cycle: - A new GPIO hogging mechanism has been added. This can be used on boards that want to drive some GPIO line high, low, or set it as input on boot and then never touch it again. For some embedded systems this is bliss and simplifies things to a great extent. - Some API cleanup and closure: gpiod_get_array() and gpiod_put_array() has been added to get and put GPIOs in bulk as was possible with the non-descriptor API. - Encapsulate cross-calls to the pin control subsystem in <linux/gpio/driver.h>. Now this should be the only header any GPIO driver needs to include or something is wrong. Cleanups restricting drivers to this include are welcomed if tested. - Sort the GPIO Kconfig and split it into submenus, as it was becoming and unstructured, illogical and unnavigatable mess. I hope this is easier to follow. Menus that require a certain subsystem like I2C can now be hidden nicely for example, still working on others. - New drivers: - New driver for the Altera Soft GPIO. - The F7188x driver now handles the F71869 and F71869A variants. - The MIPS Loongson driver has been moved to drivers/gpio for consolidation and cleanup. - Cleanups: - The MAX732x is converted to use the GPIOLIB_IRQCHIP infrastructure. - The PCF857x is converted to use the GPIOLIB_IRQCHIP infrastructure. - Radical cleanup of the OMAP driver. - Misc: - Enable the DWAPB GPIO for all architectures. This is a "hard IP" block from Synopsys which has started to turn up in so diverse architectures as X86 Quark, ARC and a slew of ARM systems. So even though it's not an expander, it's generic enough to be available for all. - We add a mock GPIO on Crystalcove PMIC after a long discussion with Daniel Vetter et al, tracing back to the shootout at the kernel summit where DRM drivers and sub-componentization was discussed. In this case a mock GPIO is assumed to be the best compromise gaining some reuse of infrastructure without making DRM drivers overly complex at the same time.
