Subject: [PATCH 3/3] smc-tools: stats: Use correct fallback counter values
|
||||
after reset
|
||||
|
||||
Fallback counters are using the merged values for the cache
|
||||
when reset is called. The cache file needs to be filled with
|
||||
absolute values as a reference point for the reset as the
|
||||
successive calls will deduct this reference point from the
|
||||
new absolute value.
