Hi David,

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

fs/btrfs/inode.c: In function 'btrfs_submit_direct':
fs/btrfs/inode.c:8467:14: warning: 'bio' may be used uninitialized in this function [-Wmaybe-uninitialized]
struct bio *bio;

I can't tell if it is a false positive or not.
