Subject: [PATCH] sysctl: Modify sysctl_overload_detect_period minimum to 100ms

hulk inclusion
category: features
bugzilla: https://gitee.com/openeuler/kernel/issues/I4UQ08
CVE: NA

--------------------------------

The sysctl_overload_detect_period indicates the maximum time that an
offline task can be preempted by online tasks. Currently, this minimum
is 1s, it is too long for the vcpu thread in VM. So set its minimum to
100ms.
