Hi, all:
I looked at the bug a little.
The issue is that in the error handling code, hso_free_net_device
unregisters
the net_device (hso_net->net) by calling unregister_netdev. In the
error handling code path,
hso_net->net has not been registered yet.

CS19 TrackPoint needn't use any Absolute (Raw) mode

Maybe here is some mis-understanding, the mouse mode here doesn't mean
we use psmouse-base.c for cs19 (bare ps/2 mouse), we plan to use

The return type of jsm_get_mstat was int, and the local var result
was for the return should be int, make the change.

The kvm_mmu_clear_all_pte_masks interface is only used by kvm_mmu_module_init
locally, and does not need to be called by other module, make it static.
This patch cleans up sparse warning:
symbol 'kvm_mmu_clear_all_pte_masks' was not declared. Should it be static?

BloodTest is for it.
It is a interface can acess function of other analysing tools and
records to internal buffer that user or application can access very
quickly (mmap).
Now, BloodTest just support record cpu, perf and task infomation in

The page add a new condition to let gfp_to_alloc_flags return
alloc_flags with ALLOC_HARDER if the order is not 0 and migratetype is
MIGRATE_UNMOVABLE.
Then alloc umovable page that order is not 0 will try to use HighAtomic.
