        leaks.

      Linus Torvalds 提交于
      Pull SCSI target updates from Nicholas Bellinger:
       "This series contains HCH's changes to absorb configfs attribute
        ->show() + ->store() function pointer usage from it's original
        tree-wide consumers, into common configfs code.
      
        It includes usb-gadget, target w/ drivers, netconsole and ocfs2
        changes to realize the improved simplicity, that now renders the
        original include/target/configfs_macros.h CPP magic for fabric drivers
        and others, unnecessary and obsolete.
      
        And with common code in place, new configfs attributes can be added
        easier than ever before.
      
        Note, there are further improvements in-flight from other folks for
        v4.5 code in configfs land, plus number of target fixes for post -rc1
        code"
      
      In the meantime, a new user of the now-removed old configfs API came in
      through the char/misc tree in commit 7bd1d409 ("stm class: Introduce
      an abstraction for System Trace Module devices").
      
      This merge resolution comes from Alexander Shishkin, who updated his stm
      class tracing abstraction to account for the removal of the old
      show_attribute and store_attribute methods in commit 51798222
      ("configfs: remove old API") from this pull.  As Alexander says about
      that patch:
      
       "There's no need to keep an extra wrapper structure per item and the
        awkward show_attribute/store_attribute item ops are no longer needed.
      
        This patch converts policy code to the new api, all the while making
        the code quite a bit smaller and easier on the eyes.
      
        Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>"
      
      That patch was folded into the merge so that the tree should be fully
      bisectable.

      Andreas Gruenbacher 提交于
      Now that the xattr handler is passed to the xattr handler operations, we
      can use the same get and set operations for the user, trusted, and security
      xattr namespaces.  In those namespaces, we can access the full attribute
      name by "reattaching" the name prefix the vfs has skipped for us.  Add a
      xattr_full_name helper to make this obvious in the code.
      
      For the "system.posix_acl_access" and "system.posix_acl_default"
      attributes, handler->prefix is the full attribute name; the suffix is the
      empty string.

      xattr handlers: Pass handler to operations instead of flags · d9a82a04
      Andreas Gruenbacher 提交于
      The xattr_handler operations are currently all passed a file system
      specific flags value which the operations can use to disambiguate between
      different handlers; some file systems use that to distinguish the xattr
      namespace, for example.  In some oprations, it would be useful to also have
      access to the handler prefix.  To allow that, pass a pointer to the handler
      to operations instead of the flags value alone.

      vfs: Fix the posix_acl_xattr_list return value · dae5f57a
      Andreas Gruenbacher 提交于
      When a filesystem that contains POSIX ACLs is mounted without ACL support
      (-o noacl), the appropriate behavior is not to list any existing POSIX ACL
      xattrs.  The return value for list xattr handlers in this case is 0, not an
      error code: several filesystems that use the POSIX ACL xattr handlers do
      not expect the list operation to fail.
      
      Symlinks cannot have ACLs, so posix_acl_xattr_list will never be called for
      symlinks in the first place.

      dax: fix __dax_pmd_fault crash · 152d7bd8
      Dan Williams 提交于
      Since 4.3 introduced devm_memremap_pages() the pfns handled by DAX may
      optionally have a struct page backing.  When a mapped pfn reaches
      vmf_insert_pfn_pmd() it fails with a crash signature like the following:
      
       kernel BUG at mm/huge_memory.c:905!
       [..]
       Call Trace:
        [<ffffffff812a73ba>] __dax_pmd_fault+0x2ea/0x5b0

        [<ffffffff811fbe02>] handle_mm_fault+0x312/0x1b50
      
      Fix this by falling back to 4K mappings in the pfn_valid() case.  Longer
      term, vmf_insert_pfn_pmd() needs to grow support for architectures that
      can provide a 'pmd_special' capability.

      drm: Don't oops in drm_calc_timestamping_constants() if drm_vblank_init() wasn't called · 0c545ac4
      Ville Syrjälä 提交于
      Seems the crtc helpers call drm_calc_timestamping_constants()
      unconditionally even if the driver didn't initialize vblank support by
      calling drm_vblank_init(). That used to be OK since the constants were
      stored under drm_crtc.
      
      However I broke this with
      commit eba1f35d ("drm: Move timestamping constants into drm_vblank_crtc")
      when I moved the constants to live inside the drm_vblank_crtc struct
      instead. If drm_vblank_init() isn't called, we don't allocate these
      structures, and so drm_calc_timestamping_constants() will oops.
      
      Fix it by adding a check into drm_calc_timestamping_constants() to see
      if vblank support was initialized at all. And to keep in line with other
      such checks, also toss in a check and warn for the case where vblank
      support was initialized, but the wrong number of crtcs was specified.
      
      Fixes the following sort of oops:

      Pull second batch of kvm updates from Paolo Bonzini:
       "Four changes:
      
         - x86: work around two nasty cases where a benign exception occurs
           while another is being delivered.  The endless stream of exceptions
           causes an infinite loop in the processor, which not even NMIs or
           SMIs can interrupt; in the virt case, there is no possibility to
           exit to the host either.
      
         - x86: support for Skylake per-guest TSC rate.  Long supported by
           AMD, the patches mostly move things from there to common
           arch/x86/kvm/ code.
      
         - generic: remove local_irq_save/restore from the guest entry and
           exit paths when context tracking is enabled.  The patches are a few
           months old, but we discussed them again at kernel summit.  Andy
           will pick up from here and, in 4.5, try to remove it from the user
           entry/exit paths.
      
         - PPC: Two bug fixes, see merge commit 37028975 for details"

      Pull more power management and ACPI updates from Rafael Wysocki:
       "The only new feature in this batch is support for the ACPI _CCA device
        configuration object, which it a pre-requisite for future ACPI PCI
        support on ARM64, but should not affect the other architectures.
      
        The rest is fixes and cleanups, mostly in cpufreq (including
        intel_pstate), the Operating Performace Points (OPP) framework and
        tools (cpupower and turbostat).
      
        Specifics:
      
         - Support for the ACPI _CCA configuration object intended to tell the
           OS whether or not a bus master device supports hardware managed
           cache coherency and a new set of functions to allow drivers to
           check the cache coherency support for devices in a platform
           firmware interface agnostic way (Suravee Suthikulpanit, Jeremy
           Linton).
      
         - ACPI backlight quirks for ESPRIMO Mobile M9410 and Dell XPS L421X
           (Aaron Lu, Hans de Goede).
      
         - Fixes for the arm_big_little and s5pv210-cpufreq cpufreq drivers
           (Jon Medhurst, Nicolas Pitre).
      
         - kfree()-related fixup for the recently introduced CPPC cpufreq
           frontend (Markus Elfring).
      
         - intel_pstate fix reducing kernel log noise on systems where
           P-states are managed by hardware (Prarit Bhargava).
      
         - intel_pstate maintainers information update (Srinivas Pandruvada).
      
         - cpufreq core optimization related to the handling of delayed work
           items used by governors (Viresh Kumar).
      
         - Locking fixes and cleanups of the Operating Performance Points
           (OPP) framework (Viresh Kumar).
      
         - Generic power domains framework cleanups (Lina Iyer).
      
         - cpupower tool updates (Jacob Tanenbaum, Sriram Raghunathan, Thomas
           Renninger).
      
         - turbostat tool updates (Len Brown)"
