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").
