--- Comment #44 from Christophe Leroy (christophe.leroy@csgroup.eu) ---
Interesting.

I wonder why it works with OUTLINE KASAN but not with INLINE KASAN.

Can you activate CONFIG_PTDUMP_DEBUGFS and provide the content of
/sys/kernel/debug/kernel_page_tables for the cases than don't work (OUTILINE
KASAN + 0x30000000 LOWMEM_SIZE, INLINE KASAN + 0x20000000 LOWMEM SIZE).
