Hmm, just to copy-up.
I have no objection this factoring-out, but do you have any specific
reason for overlayfs NOT to support i_op->tmpfile()?

If you try supporting it in the future, then the parameter open_flag may
become a problem. I guess that you will make ovl_tmpfile() (currently
not exist) to call vfs_tmpfile(), and pass dummy 0 as open_flag as
overlayfs copy-up does. But such dummy parameter will make the created
tmpfile un-linkable by a user I am afraid.
