Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Browse Source 
Pull vfs fixes from Al Viro:

 - fix orangefs handling of faults on write() - I'd missed that one back
   when orangefs was going through review.

 - readdir counterpart of "9p: cope with bogus responses from server in
   p9_client_{read,write}" - server might be lying or broken, and we'd
   better not overrun the kmalloc'ed buffer we are copying the results
   into.

 - NFS O_DIRECT read/write can leave iov_iter advanced by too much;
   that's what had been causing iov_iter_pipe() warnings davej had been
   seeing.

 - statx_timestamp.tv_nsec type fix (s32 -> u32). That one really should
   go in before 4.11.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  uapi: change the type of struct statx_timestamp.tv_nsec to unsigned
  fix nfs O_DIRECT advancing iov_iter too much
  p9_client_readdir() fix
  orangefs_bufmap_copy_from_iovec(): fix EFAULT handling
