Al,

This should address your comments.

No xfstests regressions on xfs or overlayfs.  Also tested overlayfs on
fuse.

git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git#fuse-tmpfile-v3

V3:
 - add bits to Documentation/
 - add hugetlbfs cleanup
 - overlayfs copy-up: move opening target file to caller 

V2:
 - rename finish_tmpfile() to finish_open_simple()
 - fix warning reported by kernel test robot
 - patch description improvements
