wiphy_hrtimer_work_flush(9)
π wiphy_hrtimer_work_flush(9) β like, the whole glow-up
okay so this is a page from the Kernel API Manual (section 9, bestie β we're in kernel-internals territory π§), and honestly? it's short but it matters. it's called wiphy_hrtimer_work_flush, and no cap, the name is doing exactly what it says on the tin.
β¨ NAME β¨
wiphy_hrtimer_work_flush β flush previously queued hrtimer work πβ¨
like, you queued it earlier, and now you're flushing it. that's the whole vibe check.
π SYNOPSIS π
void wiphy_hrtimer_work_flush (struct wiphy *wiphy , struct
wiphy_hrtimer_work *hrwork );
it returns void, which honestly is such main character energy β it does the thing and doesn't even feel the need to report back. okay queen π
πΈ ARGUMENTS πΈ
wiphyβ the wiphy π¦ β and bestie, this one is for debug purposes. that's it. that's its job. it's not out here doing real work, it's just there so the debug output can point at something.hrworkβ the hrtimer work to flush π₯ β this is the actual thing you're here for, the previously queued work that's about to get run.
π DESCRIPTION π
so here's the tea: this function flushes the work β and by "flushes" we mean it runs it if it's pending. not "cancels" it, not "waits around for it", it runs it. periodt. π
β οΈ okay this is the important bit, do NOT skip it: this must be called under the wiphy mutex acquired bywiphy_lock. the wiphy mutex. acquired bywiphy_lock. literally cannot stress this enough, bestie β take the lock first or you're gonna have a bad time π
more parts coming, don't go anywhere babes π«Ά
