Hi Jens,

After merging the block tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

drivers/block/loop.c: In function 'lo_splice_actor':
drivers/block/loop.c:398: warning: unused variable 'ret'

Introduced by commit a8adbe378b56acd5945df70753c7e8f6fe223304
("fs/splice: Pull buf->ops->confirm() from splice_from_pipe actors").
