Subject: linux-next: manual merge of the gfs2 tree with the vfs tree

Hi all,

Today's linux-next merge of the gfs2 tree got conflicts in:

  include/linux/uio.h
  lib/iov_iter.c

between commit:

  c8129a6f6ed1 ("sanitize iov_iter_fault_in_readable()")

from the vfs tree and commit:

  f8524fce6a88 ("iov_iter: Add iov_iter_fault_in_writeable()")

from the gfs2 tree.

I fixed it up (see below - both commits fixed up the indentation in
iov_iter_fault_in_readable()) 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
