All the other counters get reset to 0 when printing stats,
while the flush counter keeps incrementing:
[ 2118.107554] xen-blkback: (5.xvda-0): oo 0 | rd 1748 | wr 6 | f 3424 | ds 0 | pg: 161/1056
[ 2128.147524] xen-blkback: (5.xvda-0): oo 0 | rd 5705 | wr 9 | f 3429 | ds 0 | pg: 161/1056
[ 2138.179507] xen-blkback: (5.xvda-0): oo 0 | rd 137 | wr 16 | f 3433 | ds 0 | pg: 161/1056
[ 2148.187460] xen-blkback: (5.xvda-0): oo 0 | rd 0 | wr 25 | f 3448 | ds 0 | pg: 161/1056
