The first one makes this easier for you, the second and third are not
always true.  There have been big patchsets get merged into longterm
stable kernel releases that were done because they were "optimizations"
and the maintainer of that subsystem and I discussed it and deemed it
was a valid thing to accept.  This happens every 6 months or so if you
look closely.  The mm subsystem is known for this :)

so major mm subsystem optimizations will go in in the middle of a 
LTS between "random" sublevel releases ? Atleast for 4.4-4.4.13 I was not
able to pin-point such a change (based on files-changes/lines-added/removed)
could you point me to the one or other ? would help to see why we missed it.

4.4 hasn't been around long enough for this to happen yet, I think it
happened in 4.1, or maybe 3.14, or possibly 3.10, can't remember, but it
should be obvious by the changelogs.
