Henry, this is fixing a bug in the ITS. The feature is at the moment 
experiement and the code is not used by other subystem, so technically 
not necessary for 4.17. But if you still accept any bug fix (I know we 
are close to the release), then I would like to request to include. It 
should be risk free.
Cheers,

Cheers,
