From eba9f08293d76370049ec85581ab3d7f6d069e3e Mon Sep 17 00:00:00 2001 From: zhuguangqing Date: Wed, 14 Oct 2020 22:02:20 +0800 Subject: sched: Replace zero-length array with flexible-array In the following commit: 04f5c362ec6d: ("sched/fair: Replace zero-length array with flexible-array") a zero-length array cpumask[0] has been replaced with cpumask[]. But there is still a cpumask[0] in 'struct sched_group_capacity' which was missed. The point of using [] instead of [0] is that with [] the compiler will generate a build warning if it isn't the last member of a struct.
