Hi Bart,

Only the warning prefixed by '>>' is related to this commit 4ce4c73f662b:

 >> drivers/md/raid10.c:2647:60: sparse: sparse: incorrect type in 
argument 5 (different base types) @@     expected restricted blk_opf_t 
[usertype] opf @@     got int rw @@

and I can reproduce it in my system.

Best Regards,
