I'll attach a photo shortly.

I can confirm that with CONFIG_THREAD_SHIFT=14 the G4 runs good again with
INLINE KASAN + KASAN_VMALLOC enabled (as seen in attached dmesg). No KASAN hit
at raid6_pq, no poblem with btrfs.

Though with CONFIG_THREAD_SHIFT=14 + OUTLINE KASAN + KASAN_VMALLOC I still get
this KASAN hit at raid6_pq.
