clocksource_...ax_deferment(9)

💅 clocksource_...ax_deferment(9) — from the Kernel API Manual, bestie ✨

Okay so this is the whole entire page for clocksource_update_max_deferment, straight out of the Kernel API Manual (the (9) is giving kernel-doc energy, iykyk 🎀). Buckle up, it's short but it matters.

---

🌸 NAME 🌸

clocksource_update_max_deferment — Updates the clocksource max_idle_ns & max_cycles

Like, that's literally the whole job. Not me being dramatic, that's just what it does 💅

---

✨ SYNOPSIS ✨

void clocksource_update_max_deferment (struct clocksource *cs );

Returns nothing (void), takes one pointer, moves on with its life. Iconic minimalism honestly 🦋

---

🫶 ARGUMENTS 🫶

• cs — Pointer to clocksource to be updated. That's it, that's the whole input. Hand it a clocksource and it goes to work ✨

Fr fr, it's just one parameter. No sneaky extra args hiding anywhere. We checked. 💀

Bestie the reading list is LONG, so let's get into it. This all lives in Kernel file ./kernel/time/clocksource.c, and here's the whole squad:

Twenty entries. Twenty!! We did not skip a single one, that's a promise 🫡💖 Read them all or don't, but they're all here and accounted for.

🧚 Little reminder that this page only tells you it updates the clocksource max_idle_ns & max_cycles via the cs pointer — nothing more is claimed here, so don't go inventing extra behaviour, mwah 💜

Okay that's a wrap, bestie — with love from ./kernel/time, dated October 2026, in the Kernel API Manual, under the title clocksource_...ax_deferment(9). Slay, go update some deferment ✨💅
