[PATCH 37/49] arch/mips: replace cpumask_weight with cpumask_weight_{eq, ...} where appropriate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Mips code uses calls cpumask_weight() to compare the weight of cpumask
with a given number. We can do it more efficiently with
cpumask_weight_{eq, ...} because conditional cpumask_weight may stop
traversing the cpumask earlier, as soon as condition is (or can't be) met.
