Hi Ira,
I applied your patch set on my branch but ibv_reg_mr() with /dev/dax0.0
didn't trigger any warning or panic after enabling DEVMAP_ACCESS_PROTECTION.
PS: ibv_reg_mr() calls page_address() in kernel.
Do you know if some hardwares(e.g. CPU) need to support PKS feature? how
to check the feature on hardwares? or do I need more steps?
Best Regards,
Xiao Yang
