Subjectfs/btrfs/inode.c:6039: warning: ‘bio’ is used un initialized in this function
From
fs/btrfs/inode.c: In function ‘btrfs_submit_direct_hook’:
fs/btrfs/inode.c:6039: warning: ‘bio’ is used uninitialized in this function

`BIO_BUG_ON(!atomic_read(&bio->bi_cnt))' in bio_put() later will blow up nicely
when passed a random pointer on the stack.

Introduced by commit 02f57c7aedef1a537f4b16db7061cdd8efa3bb4e
("Btrfs: don't split dio bios if we don't have to").

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
