Hmm... This looks to me like it is rather an ext4 bug. Reassigning to
the ext4 folks for the moment.

Hmm we are doing dquot_reserve_space with i_block_reservation_lock held.
ie
spin_lock(&EXT4_I(inode)->i_block_reservation_lock);
- vfs_dq_reserve_block
- down_read(&sb_dqopt(inode->i_sb)->dqptr_sem)
