Hi Zach,

FYI, there are new sparse warnings show up in

tree:   git://github.com/kleikamp/linux-shaggy loop_v3
head:   d6e600319940e6015af553f1515cee9d53a3ced9
commit: c6aadd9b8fd4039534075531b06c8dc263f27c9d [16/22] loop: use aio to perform io on the underlying file

+ drivers/block/loop.c:217:6: sparse: symbol 'lo_rw_aio_complete' was not declared. Should it be static?
  drivers/block/loop.c:270:38: sparse: incorrect type in argument 2 (different address spaces)
  drivers/block/loop.c:270:38:    expected char const [noderef] <asn:1>*<noident>
  drivers/block/loop.c:270:38:    got unsigned char [usertype] *buf
