       - fix io_destroy()/aio_complete() race
      
       - the vfs_open() change to get rid of open_check_o_direct() boilerplate
         was nice, but buggy. Al has a patch avoiding a revert, but that's
         definitely not a last-day fodder, so for now revert it is...

      This reverts commit cab64df1.
      
      Having vfs_open() in some cases drop the reference to
      struct file combined with
      
      	error = vfs_open(path, f, cred);
      	if (error) {
      		put_filp(f);
      		return ERR_PTR(error);
      	}
      	return f;
      
      is flat-out wrong.  It used to be
      
      		error = vfs_open(path, f, cred);
      		if (!error) {
      			/* from now on we need fput() to dispose of f */
      			error = open_check_o_direct(f);
      			if (error) {
      				fput(f);
      				f = ERR_PTR(error);
      			}
      		} else {
      			put_filp(f);
      			f = ERR_PTR(error);
      		}
      
      and sure, having that open_check_o_direct() boilerplate gotten rid of is
      nice, but not that way...
      
      Worse, another call chain (via finish_open()) is FUBAR now wrt
      FILE_OPENED handling - in that case we get error returned, with file
      already hit by fput() *AND* FILE_OPENED not set.  Guess what happens in
      path_openat(), when it hits
      
      	if (!(opened & FILE_OPENED)) {
      		BUG_ON(!error);
      		put_filp(file);
      	}
      
      The root cause of all that crap is that the callers of do_dentry_open()
      have no way to tell which way did it fail; while that could be fixed up
      (by passing something like int *opened to do_dentry_open() and have it
      marked if we'd called ->open()), it's probably much too late in the
      cycle to do so right now.

      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"

      net: ethernet: davinci_emac: fix error handling in probe() · 8005b09d
      Dan Carpenter authored
      The current error handling code has an issue where it does:
      
      	if (priv->txchan)
      		cpdma_chan_destroy(priv->txchan);
      
      The problem is that ->txchan is either valid or an error pointer (which
      would lead to an Oops).  I've changed it to use multiple error labels so
      that the test can be removed.
      
      Also there were some missing calls to netif_napi_del().
