This kernel is base on 4.4.6 version and just add a patch from 4.6.
the patching reason is we faced deadlock issue in 4.4.6. the detail :
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=822084;msg=5
the kernel we use is stable for a long time. but recently we start to
use fuse, face this kernel panic issue. but I can not find any
information be related to fuse module.
