[PATCH] ext3 filesystem bogus ENOSPC with reservation fix
To handle the earlier bogus ENOSPC error caused by filesystem full of block reservation, current code falls back to non block reservation, starts to allocate block(s) from the goal allocation block group as if there is no block reservation. Current code needs to re-load the corresponding block group descriptor for the initial goal block group in this case. The patch fixes this.
