Here are leftover pieces now rebased on top of next/stable:

https://github.com/ereshetova/linux-stable/commits/refcount_t_fs
https://github.com/ereshetova/linux-stable/commits/refcount_t_block

Haven't tested them beyond allyesconfig compile through...

There are also mm pieces (ignore bdi_writeback_congested.refcnt as it is already done)
 that were sent originally here:
https://lore.kernel.org/lkml/1487671124-11188-1-git-send-email-elena.reshetova@intel.com/
But especially mm_struct pieces would need a new look and proper 
checks. 
Again, happy to do them also on a separate branch, if there is an interest to merge
them (I expect mm_struct to be much more sensitive structure for such changes).

Best Regards,
Elena
