      refcount: change EXPORT_SYMBOL markings · d557d1b5
      Greg Kroah-Hartman 提交于
      Now that kref is using the refcount apis, the _GPL markings are getting
      exported to places that it previously wasn't.  Now kref.h is GPLv2
      licensed, so any non-GPL code using it better be talking to some
      lawyers, but changing api markings isn't considered "nice", so let's fix
      this up.

      docs: bump minimal GNU Make version to 3.81 · 37d69ee3
      Masahiro Yamada 提交于
      Since 2014, you can't successfully build kernels with GNU Make version
      3.80. Example errors:
      
        $ git describe
        v4.11
        $ make --version | head -1
        GNU Make 3.80
        $ make defconfig
          HOSTCC  scripts/basic/fixdep
        scripts/Makefile.host:135: *** missing separator.  Stop.
        make: *** [defconfig] Error 2
        $ make ARCH=arm64 help
        arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'.  Stop.
        $ make help >/dev/null
        ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive
        ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional.  Stop.
        make: *** [help] Error 2
      
      The first breakage was introduced by commit c8589d1e ("kbuild:
      handle multi-objs dependency appropriately").  Since then (i.e. v3.18),
      GNU Make 3.80 has not been able to compile the kernel, but nobody has
      ever complained aboutt (or noticed) it.
      
      Even GNU Make 3.81 is more than 10 years old.  It would not hurt to
      match the documentation with reality instead of fixing makefiles.

      initramfs: avoid "label at end of compound statement" error · 394e4f5d
      Linus Torvalds 提交于
      Commit 17a9be31 ("initramfs: Always do fput() and load modules after
      rootfs populate") introduced an error for the
      
          CONFIG_BLK_DEV_RAM=y
      
      case, because even though the code looks fine, the compiler really wants
      a statement after a label, or you'll get complaints:
      
        init/initramfs.c: In function 'populate_rootfs':
        init/initramfs.c:644:2: error: label at end of compound statement
      
      That commit moved the subsequent statements to outside the compound
      statement, leaving the label without any associated statements.

      Linus Torvalds 提交于
      Pull libnvdimm updates from Dan Williams:
       "The bulk of this has been in multiple -next releases. There were a few
        late breaking fixes and small features that got added in the last
        couple days, but the whole set has received a build success
        notification from the kbuild robot.
      
        Change summary:
      
         - Region media error reporting: A libnvdimm region device is the
           parent to one or more namespaces. To date, media errors have been
           reported via the "badblocks" attribute attached to pmem block
           devices for namespaces in "raw" or "memory" mode. Given that
           namespaces can be in "device-dax" or "btt-sector" mode this new
           interface reports media errors generically, i.e. independent of
           namespace modes or state.
      
           This subsequently allows userspace tooling to craft "ACPI 6.1
           Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error"
           requests and submit them via the ioctl path for NVDIMM root bus
           devices.
      
         - Introduce 'struct dax_device' and 'struct dax_operations': Prompted
           by a request from Linus and feedback from Christoph this allows for
           dax capable drivers to publish their own custom dax operations.
           This fixes the broken assumption that all dax operations are
           related to a persistent memory device, and makes it easier for
           other architectures and platforms to add customized persistent
           memory support.
      
         - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
           available for storage appliance applications to manually trigger
           memory controllers to drain write-pending buffers that would
           otherwise be flushed automatically by the platform ADR
           (asynchronous-DRAM-refresh) mechanism at a power loss event.
           Support for "locked" DIMMs is included to prevent namespaces from
           surfacing when the namespace label data area is locked. Finally,
           fixes for various reported deadlocks and crashes, also tagged for
           -stable.
      
         - ACPI / nfit driver updates: General updates of the nfit driver to
           add DSM command overrides, ACPI 6.1 health state flags support, DSM
           payload debug available by default, and various fixes.

        a new crypto accelerator.
      
        We also deleted a bunch of stuff, mostly in patch cleanups, but also
        the Android ION code has shrunk a lot, and the Android low memory
        killer driver was finally deleted, much to the celebration of the -mm

      Pull media updates from Mauro Carvalho Chehab:
       "Media updates for v4.12-rc1:
      
         - new driver to support mediatek jpeg in hardware codec
      
         - rc-lirc, s5p-cec and st-cec staging drivers got promoted
      
         - hardware histogram support for vsp1 driver
      
         - added Virtual Media Controller driver, to make easier to test the
           media controller
      
         - added a new CEC driver (rainshadow-cec)
      
         - removed two staging LIRC drivers for obscure hardware that are too
           obsolete
      
         - added support for Intel SR300 Depth camera
      
         - some improvements at CEC and RC core
      
         - lots of driver cleanups, improvements all over the tree
      
        With this series, we're finally getting rid of the LIRC staging
        driver. There's just one left (lirc_zilog), with require more care,
        as part of its functionality (IR RX) is already provided by another
        driver. Work in progress to convert it on the proper way"

      Linus Torvalds 提交于
      Pull GFS2 updates from Bob Peterson:
       "We've got ten GFS2 patches for this merge window.
      
         - Andreas Gruenbacher wrote a patch to replace the deprecated call to
           rhashtable_walk_init with rhashtable_walk_enter.
      
         - Andreas also wrote a patch to eliminate redundant code in two of
           our debugfs sequence files.
      
         - Andreas also cleaned up the rhashtable key ugliness Linus pointed
           out during this cycle, following Linus's suggestions.
      
         - Andreas also wrote a patch to take advantage of his new function
           rhashtable_lookup_get_insert_fast. This makes glock lookup faster
           and more bullet-proof.
      
         - Andreas also wrote a patch to revert a patch in the evict path that
           caused occasional deadlocks, and is no longer needed.
      
         - Andrew Price wrote a patch to re-enable fallocate for the rindex
           system file to enable gfs2_grow to grow properly on secondary file
           system grow operations.
      
         - I wrote a patch to initialize an inode number field to make certain
           kernel trace points more understandable.
      
         - I also wrote a patch that makes GFS2 file system "withdraw" work
           more like it should by ignoring operations after a withdraw that
           would formerly cause a BUG() and kernel panic.
      
         - I also reworked the entire truncate/delete algorithm, scrapping the
           old recursive algorithm in favor of a new non-recursive algorithm.
           This was done for performance: This way, GFS2 no longer needs to
           lock multiple resource groups while doing truncates and deletes of
           files that cross multiple resource group boundaries, allowing for
           better parallelism. It also solves a problem whereby deleting large
           files would request a large chunk of kernel memory, which resulted
           in a get_page_from_freelist warning.
      
         - Due to a regression found during testing, I added a new patch to
           correct 'GFS2: Prevent BUG from occurring when normal Withdraws
           occur'."

      Pull orangefs updates from Mike Marshall:
       "Orangefs cleanups, fixes and statx support.
      
        Some cleanups:
      
         - remove unused get_fsid_from_ino
         - fix bounds check for listxattr
         - clean up oversize xattr validation
         - do not set getattr_time on orangefs_lookup
         - return from orangefs_devreq_read quickly if possible
         - do not wait for timeout if umounting
         - handle zero size write in debugfs
      
        Bug fixes:
      
         - do not check possibly stale size on truncate
         - ensure the userspace component is unmounted if mount fails
         - total reimplementation of dir.c
      
        New feature:
      
         - implement statx
      
        The new implementation of dir.c is kind of a big deal, all new code.
        It has been posted to fs-devel during the previous rc period, we
        didn't get much review or feedback from there, but it has been
        reviewed very heavily here, so much so that we have two entire
        versions of the reimplementation.
      
        Not only does the new implementation fix some xfstests, but it passes
        all the new tests we made here that involve seeking and rewinding and
        giant directories and long file names. The new dir code has three
        patches itself:
      
         - skip forward to the next directory entry if seek is short
         - invalidate stored directory on seek
         - count directory pieces correctly"
