[Xen-devel] [PATCH] xen-blkback: reset flush counter for log_stats

[Valentin Vidic <Valentin.Vidic@xxxxxxxxx>]

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
