tmpfs: add accurate compare function to percpu_counter library ...
Add percpu_counter_compare that allows for a quick but accurate comparison
of percpu_counter with a given value.
A rough count is provided by the count field in percpu_counter structure,
without accounting for the other values stored in individual cpu counters.
The actual count is a sum of count and the cpu counters. However, count
field is never different from the actual value by a factor of
batch*num_online_cpu. We do not need to get actual count for comparison
if count is different from the given value by this factor and allows for
quick comparison without summing up all the per cpu counters.
