      Pull xfs fix from Darrick Wong:
       "Clear out i_mapping error state when we're reinitializing inodes.
      
        This last minute fix prevents writeback error state from persisting
        past the end of the in-core inode lifecycle and causing EIO errors to
        be reported to userspace when no error has occurred.
      
        This fix for the behavioral regression has been soaking in for-next
        for a while, but various fs developers persuaded me to try to get it
        upstream for 4.17 because the patch that broke things was introduced
        in 4.17-rc4"

      Pull x86 platform driver fix from Andy Shevchenko:
       "Fix NULL pointer dereference in asus-wmi on rfkill cleanup.
      
        The effective change is just one new condition - two lines of code.
        But it required moving one static helper function, which is why the
        diff looks a bit bigger"

      Do not perform the rfkill cleanup routine when
      (asus->driver->wlan_ctrl_by_user && ashs_present()) is true, since
      nothing is registered with the rfkill subsystem in that case. Doing so
      leads to the following kernel NULL pointer dereference:

      fs: clear writeback errors in inode_init_always · 829bc787
      Darrick J. Wong authored
      In inode_init_always(), we clear the inode mapping flags, which clears
      any retained error (AS_EIO, AS_ENOSPC) bits.  Unfortunately, we do not
      also clear wb_err, which means that old mapping errors can leak through
      to new inodes.
      
      This is crucial for the XFS inode allocation path because we recycle old
      in-core inodes and we do not want error state from an old file to leak
      into the new file.  This bug was discovered by running generic/036 and
      generic/047 in a loop and noticing that the EIOs generated by the
      collision of direct and buffered writes in generic/036 would survive the
      remount between 036 and 047, and get reported to the fsyncs (on
      different files!) in generic/047.
