Subject: linux-next: manual merge of the vfs tree with the orangefs tree

From: Stephen Rothwell <[email-masked]>

Hi all,

Today's linux-next merge of the vfs tree got a conflict in:

  fs/orangefs/super.c

between commit:

  77becb76042a ("orangefs: implement xattr cache")

from the orangefs tree and commit:

  f276ae0dd6d0 ("orangefs: make use of ->free_inode()")

from the vfs tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
