Pull ceph updates from Ilya Dryomov: "The two main items are support for disabling automatic rbd exclusive lock transfers from myself and the long awaited -ENOSPC handling series from Jeff. The former will allow rbd users to take advantage of exclusive lock's built-in blacklist/break-lock functionality while staying in control of who owns the lock. With the latter in place, we will abort filesystem writes on -ENOSPC instead of having them block indefinitely.

2017-05-11uapi: export all arch specifics directoriesNicolas Dichtel
This patch removes the need of subdir-y. Now all files/directories under arch/<arch>/include/uapi/ are exported. The only change for userland is the layout of the command 'make headers_install_all': directories asm-<arch> are replaced by arch-<arch>/. Those new directories contains all files/directories of the specified arch. Note that only cris and tile have more directories than only asm: - arch-v[10|32] for cris; - arch for tile.

2017-05-11uapi: export all headers under uapi directoriesNicolas Dichtel
Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After this patch, the following files, which were not exported, are now exported (with make headers_install_all): asm-arc/kvm_para.h asm-arc/ucontext.h asm-blackfin/shmparam.h asm-blackfin/ucontext.h asm-c6x/shmparam.h asm-c6x/ucontext.h asm-cris/kvm_para.h asm-h8300/shmparam.h asm-h8300/ucontext.h asm-hexagon/shmparam.h asm-m32r/kvm_para.h asm-m68k/kvm_para.h asm-m68k/shmparam.h asm-metag/kvm_para.h asm-metag/shmparam.h asm-metag/ucontext.h asm-mips/hwcap.h asm-mips/reg.h asm-mips/ucontext.h asm-nios2/kvm_para.h asm-nios2/ucontext.h asm-openrisc/shmparam.h asm-parisc/kvm_para.h asm-powerpc/perf_regs.h asm-sh/kvm_para.h asm-sh/ucontext.h asm-tile/shmparam.h asm-unicore32/shmparam.h asm-unicore32/ucontext.h asm-x86/hwcap2.h asm-xtensa/kvm_para.h drm/armada_drm.h drm/etnaviv_drm.h drm/vgem_drm.h linux/aspeed-lpc-ctrl.h linux/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/can/vxcan.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/cryptouser.h linux/fsmap.h linux/genwqe/genwqe_card.h linux/hash_info.h linux/kcm.h linux/kcov.h linux/kfd_ioctl.h linux/lightnvm.h linux/module.h linux/nbd-netlink.h linux/nilfs2_api.h linux/nilfs2_ondisk.h linux/nsfs.h linux/pr.h linux/qrtr.h linux/rpmsg.h linux/sched/types.h linux/sed-opal.h linux/smc.h linux/smc_diag.h linux/stm.h linux/switchtec_ioctl.h linux/vfio_ccw.h linux/wil6210_uapi.h rdma/bnxt_re-abi.h Note that I have removed from this list the files which are generated in every exported directories (like .install or .install.cmd).

2017-05-10block, bfq: stress that low_latency must be off to get max throughputPaolo Valente
The introduction of the BFQ and Kyber I/O schedulers has triggered a new wave of I/O benchmarks. Unfortunately, comments and discussions on these benchmarks confirm that there is still little awareness that it is very hard to achieve, at the same time, a low latency and a high throughput. In particular, virtually all benchmarks measure throughput, or throughput-related figures of merit, but, for BFQ, they use the scheduler in its default configuration. This configuration is geared, instead, toward a low latency. This is evidently a sign that BFQ documentation is still too unclear on this important aspect. This commit addresses this issue by stressing how BFQ configuration must be (easily) changed if the only goal is maximum throughput.

2017-05-10perf/callchain: Force USER_DS when invoking perf_callchain_user()Will Deacon
Perf can generate and record a user callchain in response to a synchronous request, such as a tracepoint firing. If this happens under set_fs(KERNEL_DS), then we can end up walking the user stack (and dereferencing/saving whatever we find there) without the protections usually afforded by checks such as access_ok. Rather than play whack-a-mole with each architecture's stack unwinding implementation, fix the root of the problem by ensuring that we force USER_DS when invoking perf_callchain_user from the perf core.

2017-05-09nfsd: fix undefined behavior in nfsd4_layout_verifyAri Kauppi
UBSAN: Undefined behaviour in fs/nfsd/nfs4proc.c:1262:34 shift exponent 128 is too large for 32-bit type 'int' Depending on compiler+architecture, this may cause the check for layout_type to succeed for overly large values (which seems to be the case with amd64). The large value will be later used in de-referencing nfsd4_layout_ops for function pointers.

2017-05-09pNFS/flexfiles: Always attempt to call layoutstats when flexfiles is enabledTrond Myklebust
Layoutstats is always desirable when using the flexfiles driver, so we should enable it if that driver is being loaded. It is safe to do so, because even when the mount specifies NFSv4.1, we will turn it off if the server tells us it is unsupported. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

It turns out the Linux server has a bug in its implementation of supattr_exclcreat; it returns the set of all attributes, whether or not they are supported by minor version 1. In order to avoid a regression, we therefore apply the supported_attrs as a mask on top of whatever the server sent us.

When any of the functions contained in NGbzero.S and GENbzero.S vector through *bzero_from_clear_user, we may end up taking a fault when executing one of the store alternate address space instructions. If this happens, the exception handler does not restore the %asi register.

But an unaligned write of 2-7 bytes can still cover two cache lines, so make sure we flush both in that case.
