      PCI: Add PTM clock granularity information · 8b2ec318
      Bjorn Helgaas authored
      The PTM Control register (PCIe r3.1, sec 7.32.3) contains an Effective
      Granularity field:
      
        This provides information relating to the expected accuracy of the PTM
        clock, but does not otherwise affect the PTM mechanism.
      
      Set the Effective Granularity based on the PTM Root and any intervening PTM
      Time Sources.
      
      This does not set Effective Granularity for Root Complex Integrated
      Endpoints because I don't know how to figure out clock granularity for
      them.  The spec says:
      
        ... system software must set [Effective Granularity] to the value
        reported in the Local Clock Granularity field by the associated PTM
        Time Source.
      
      but I don't know how to identify the associated PTM Time Source.  Normally
      it's the upstream bridge, but an integrated endpoint has no upstream
      bridge.

      PCI: pciehp: Make explicitly non-modular · 70626d88
      Paul Gortmaker authored
      This code is not being built as a module by anyone:
      
        obj-$(CONFIG_HOTPLUG_PCI_PCIE)          += pciehp.o
        pciehp-objs                             := pciehp_core.o   \
      
        drivers/pci/pcie/Kconfig:config HOTPLUG_PCI_PCIE
        drivers/pci/pcie/Kconfig:  bool "PCI Express Hotplug driver"
      
      Remove uses of MODULE_DESCRIPTION(), MODULE_AUTHOR(), MODULE_LICENSE(),
      etc., so that when reading the driver there is no doubt it is builtin-only.
      The information is preserved in comments at the top of the file.
      
      Note that for non-modular code, module_init() translates to
      device_initcall().  One could argue that we should use subsys_initcall()
      here, but for now we stick with runtime equivalence.
      
      We delete module.h but we keep the moduleparam.h include, since we are
      keeping the module_param() that the file has as-is for now.

      Remove orphaned exit function in cpci_hotplug_core.c.
      
      Note that for non-modular code, module_init() translates to
      device_initcall().  One could argue that we should use subsys_initcall()
      here, but for now we stick with runtime equivalence.
      
      We would delete module.h and just keep the moduleparam.h include (since the
      file does use module_param), but there is a try_module_get and module_put
      pairing that prevents us from doing that.

      The information is preserved in comments at the top of the file.
      
      Explicitly disallow driver unbind, since that doesn't have a sensible use
      case anyway, and it allows us to drop the ".remove" code for non-modular
      drivers.  Delete several functions only used by the remove function.
      
      Note that for non-modular code, builtin_platform_driver() uses the same
      init level priority as module_platform_driver(), so this doesn't change
      init ordering.

      PCI/PME: Make explicitly non-modular · d7def204
      Paul Gortmaker authored
      This code is not being built as a module by anyone:
      
        config PCIE_PME
              def_bool y
              depends on PCIEPORTBUS && PM
      
      Remove traces of modularity so that when reading the driver there is no
      doubt it is builtin-only.
      
      Also delete the .remove function, since that doesn't seem to have a
      sensible use case.  With "normal" endpoint drivers, we have in the past set
      the suppress_bind_attrs bit to make it clear that the use of ".remove" in a
      builtin driver was deleted, but here for PCI, it seems overkill to jump
      through the pcie_port_service_driver and into the struct device_driver in
      order to finally try and do something similar with the bind setting.
      
      Note that for non-modular code, module_init() translates to
      device_initcall().

      block: rename bio bi_rw to bi_opf · 1eff9d32
      Jens Axboe authored
      Since commit 63a4cc24, bio->bi_rw contains flags in the lower
      portion and the op code in the higher portions. This means that
      old code that relies on manually setting bi_rw is most likely
      going to be broken. Instead of letting that brokeness linger,
      rename the member, to force old and out-of-tree code to break
      at compile time instead of at runtime.
      
      No intended functional changes in this commit.

      block/mm: make bdev_ops->rw_page() take a bool for read/write · c11f0c0b
      Jens Axboe authored
      Commit abf54548 changed it from an 'rw' flags type to the
      newer ops based interface, but now we're effectively leaking
      some bdev internals to the rest of the kernel. Since we only
      care about whether it's a read or a write at that level, just
      pass in a bool 'is_write' parameter instead.
      
      Then we can also move op_is_write() and friends back under
      CONFIG_BLOCK protection.

      fs: return EPERM on immutable inode · 337684a1
      Eryu Guan authored
      In most cases, EPERM is returned on immutable inode, and there're only a
      few places returning EACCES. I noticed this when running LTP on
      overlayfs, setxattr03 failed due to unexpected EACCES on immutable
      inode.
      
      So converting all EACCES to EPERM on immutable inode.

      Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
      
      Pull more xfs updates from Dave Chinner:
       "This is the second part of the XFS updates for this merge cycle, and
        contains the new reverse block mapping feature for XFS.
      
        Reverse mapping allows us to track the owner of a specific block on
        disk precisely.  It is implemented as a set of btrees (one per
        allocation group) that track the owners of allocated extents.
        Effectively it is a "used space tree" that is updated when we allocate
        or free extents.  i.e. it is coherent with the free space btrees we
        already maintain and never overlaps with them.
      
        This reverse mapping infrastructure is the building block of several
        upcoming features - reflink, copy-on-write data, dedupe, online
        metadata and data scrubbing, highly accurate bad sector/data loss
        reporting to users, and significantly improved reconstruction of
        damaged and corrupted filesystems.  There's a lot of new stuff coming
        along in the next couple of cycles,a nd it all builds in the rmap
        infrastructure.
      
        As such, it's a huge chunk of new code with new on-disk format
        features and internal infrastructure.  It warns at mount time as an
        experimental feature and that it may eat data (as we do with all new
        on-disk features until they stabilise).  We have not released
        userspace suport for it yet - userspace support currently requires
        download from Darrick's xfsprogs repo and build from source, so the
        access to this feature is really developer/tester only at this point.
        Initial userspace support will be released at the same time kernel
        with this code in it is released.
      
        The new rmap enabled code regresses 3 xfstests - all are ENOSPC
        related corner cases, one of which Darrick posted a fix for a few
        hours ago.  The other two are fixed by infrastructure that is part of
        the upcoming reflink patchset.  This new ENOSPC infrastructure
        requires a on-disk format tweak required to keep mount times in
        check - we need to keep an on-disk count of allocated rmapbt blocks so
        we don't have to scan the entire btrees at mount time to count them.
      
        This is currently being tested and will be part of the fixes sent in
        the next week or two so users will not be exposed to this change"
