     "This the bunch that sat in -next + lock_parent() fix.  This is the
      minimal set; there's more pending stuff.
      In particular, I really hope to get acct.c fixes merged this cycle -
      we need that to deal sanely with delayed-mntput stuff.  In the next
      pile, hopefully - that series is fairly short and localized
      (kernel/acct.c, fs/super.c and fs/namespace.c).  In this pile: more
      iov_iter work.  Most of prereqs for ->splice_write with sane locking
      order are there and Kent's dio rewrite would also fit nicely on top of
      this pile"

    ->splice_write() via ->write_iter()
    iter_file_splice_write() - a ->splice_write() instance that gathers the
    pipe buffers, builds a bio_vec-based iov_iter covering those and feeds
    it to ->write_iter().  A bunch of simple cases coverted to that...

commit 23adbe12ef7d3d4195e80800ab36b37bee28cd03
Author: Andy Lutomirski <luto@xxxxxxxxxxxxxx>
Date:   Tue Jun 10 12:45:42 2014 -0700

    fs,userns: Change inode_capable to capable_wrt_inode_uidgid
    The kernel has no concept of capabilities with respect to inodes; inodes
    exist independently of namespaces.  For example, inode_capable(inode,
    CAP_LINUX_IMMUTABLE) would be nonsense.
    This patch changes inode_capable to check for uid and gid mappings and
    renames it to capable_wrt_inode_uidgid, which should make it more
    obvious what it does.
    Fixes CVE-2014-4014.

    xfs: trim the argument lists of xfs_file_{dio,buffered}_aio_write()
    pos is redundant (it's iocb->ki_pos), and iov/nr_segs/count are taken
    care of by lifting iov_iter into the caller.

    Now It Can Be Done(tm) - we don't need to do iov_shorten() in
    generic_file_direct_write() anymore, now that all ->direct_IO()
    instances are converted to proper iov_iter methods and honour
    iter->count and iter->iov_offset properly.
    Get rid of count/ocount arguments of generic_file_direct_write(),
    while we are at it.

    start adding the tag to iov_iter
    For now, just use the same thing we pass to ->direct_IO() - it's all
    iovec-based at the moment.  Pass it explicitly to iov_iter_init() and
    account for kvec vs. iovec in there, by the same kludge NFS ->direct_IO()

    kill generic_segment_checks()
    all callers of ->aio_read() and ->aio_write() have iov/nr_segs already
    checked - generic_segment_checks() done after that is just an odd way
    to spell iov_length().
