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

Hi all,

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

  fs/xfs/xfs_ioctl.c

between commits:

  ceaf603c7024 ("xfs: move the di_projid field to struct xfs_inode")
  031474c28a3a ("xfs: move the di_extsize field to struct xfs_inode")
  b33ce57d3e61 ("xfs: move the di_cowextsize field to struct xfs_inode")
  4800887b4574 ("xfs: cleanup xfs_fill_fsxattr")
  ee7b83fd365e ("xfs: use a union for i_cowextsize and i_flushiter")
  db07349da2f5 ("xfs: move the di_flags field to struct xfs_inode")
  3e09ab8fdc4d ("xfs: move the di_flags2 field to struct xfs_inode")

from the xfs tree and commit:

  280cad4ac884 ("xfs: convert to fileattr")

from the vfs tree.

I fixed it up (I think - 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,
