Hi Richard

It is generally unwanted.

Have you tried back porting patches when the directory structure has
changed? Files have moved around? It makes it a lot harder to
do. Meaning patches are going to be back ported less often. Fixes
which could be security relevant might not get back ported, etc.

Kernel 4.4 is going to be supported until 2022. So moving files around
is going to make Greg Kroah-Hartman life more difficult for the next 5
years.
