Adding a sched_class after the removal of ".next" regarding priority

Hi,
I have been trying to add a new scheduler to the Linux kernel. I have
found that to add a sched_class, I need to add it to SCHED_DATA in
vmlinux.lds.h. instead of editing the now removed .next variable.
Depending on what order I put into the priority list, it will crash
the kernel during the booting process after rebooting. Any tips on
what could be causing this would be appreciated!
Currently this works
#define SCHED_DATA \
STRUCT_ALIGN(); \
__begin_sched_classes = .; \
*(__idle_sched_class) \
*(__my_sched_class) \
*(__fair_sched_class) \
*(__rt_sched_class) \
*(__dl_sched_class) \
*(__stop_sched_class) \
__end_sched_classes = .;
While this does not
#define SCHED_DATA \
STRUCT_ALIGN(); \
__begin_sched_classes = .; \
*(__idle_sched_class) \
*(__fair_sched_class) \
*(__my_sched_class) \
*(__rt_sched_class) \
*(__dl_sched_class) \
*(__stop_sched_class) \
__end_sched_classes = .;
Regards
Jacob
