Request for help - Fix issue backport query.

Hi all,

I am extremely sorry for this query.

The issue "mnt_vnode_next_active: use conventional lock order when trylock
fails." exists in 11.4 too but I noticed that it is not being ported to
11.4, but ported only till 12.0 Reference commit:

May I request you to please share the reason for porting it only till 12.0
but not in 11.4 though the issue exists in 11.4.

I had noticed that other fixes like the below are ported to 11.4 though
(which are ported after May 15, 2017)
