To be able to reserve the tag storage associated with a page requires that the tag storage page can be migrated.When HW KASAN is enabled, the kernel allocates pages, which are now tagged, in non-preemptible contexts, which can make reserving the associate tag storage impossible.
I assume that it's the only in-kernel user that actually requires tagged memory (besides for user space), correct?
