      ipc,sem: fix semctl(..., GETZCNT) · ebc2e5e6
      Rik van Riel authored
      The semctl GETZCNT returns the number of semops waiting for the
      specified semaphore to become zero.  After commit 9f1bc2c9
      ("ipc,sem: have only one list in struct sem_queue"), the semops waiting
      on just one semaphore are waiting on that semaphore's list.
      In order to return the correct count, we have to walk that list too, in
      addition to the sem_array's list for complex operations.
      This bug broke dbench; it works again with this patch applied.

      Pull btrfs update from Chris Mason:
       "These are mostly fixes.  The biggest exceptions are Josef's skinny
        extents and Jan Schmidt's code to rebuild our quota indexes if they
        get out of sync (or you enable quotas on an existing filesystem).
        The skinny extents are off by default because they are a new variation
        on the extent allocation tree format.  btrfstune -x enables them, and
        the new format makes the extent allocation tree about 30% smaller.
        I rebased this a few days ago to rework Dave Sterba's crc checks on
        the super block, but almost all of these go back to rc6, since I
        though 3.9 was due any minute.
        The biggest missing fix is the tracepoint bug that was hit late in
        3.9.  I ran into problems with that in overnight testing and I'm still
        tracking it down.  I'll definitely have that fixed for rc2."

      watchdog: Fix race condition in registration code · 60403f7a
      Guenter Roeck authored
      A race condition exists when registering the first watchdog device.
      Sequence of events:
      - watchdog_register_device calls watchdog_dev_register
      - watchdog_dev_register creates the watchdog misc device by calling
        At that time, the matching character device (/dev/watchdog0) does not yet
        exist, and old_wdd is not set either.
      - Userspace gets an event and opens /dev/watchdog
      - watchdog_open is called and sets wdd = old_wdd, which is still NULL,
        and tries to dereference it. This causes the kernel to panic.
      Seen with systemd trying to open /dev/watchdog immediately after
      it was created.

      Use the newly introduced devm_ioremap_resource() instead of

      devm_ioremap_resource() provides its own error messages; so all explicit
