Hi,

your "kernel BUG at fs/btrfs/inode.c:3142!" from 3.19-rc4 corresponds to 
http://marc.info/?l=linux-btrfs&m=141903172106342&w=2 - it was "kernel 
BUG at /home/apw/COD/linux/fs/btrfs/inode.c:3123!" in 3.18.1, and is 
exactly the same code in both cases:


         /* grab metadata reservation from transaction handle */
         if (reserve) {
                 ret = btrfs_orphan_reserve_metadata(trans, inode);
                 BUG_ON(ret); /* -ENOSPC in reservation; Logic error? JDM 
*/
         }
