Subject: [PATCH] rtmutex: Drop pointless static qualifier in rt_mutex_adjust_prio_chain()
Date: Tue, 7 Aug 2018 08:56:03 +0000 [thread overview]
Message-ID: <1533632163-93769-1-git-send-email-maowenan@huawei.com> (raw)
There is no need to have the 'T *v' variable static
since new value always be assigned before use it.
