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

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.
