✨ scx_is_descendant(9) ✨

okay so bestie, we're in the Kernel API Manual today and the page we're looking at is scx_is_descendant(9) — yes that's the whole title situation, and honestly? iconic name, zero notes 💅

🌸 NAME 🌸

scx_is_descendant — literally just: "Test whether sched is a descendant" 🫶

✨ SYNOPSIS ✨

bool scx_is_descendant (struct scx_sched *sch , struct scx_sched
*ancestor );

that's the whole vibe check, no cap 🔥

🎀 ARGUMENTS 🎀

  • sch — the sched you're testing, the main character of this little investigation 👑
  • ancestor — the ancestor sched you're testing against, aka the "is this your grandma" reference point 🌈

💖 DESCRIPTION 💖

So here's the tea: scx_is_descendant tests whether sch is a descendant of ancestor. That's it. That's the function. Short king behavior fr fr 🦋

💀 SEE ALSO 💀

okay this list is long — like, "not me scrolling for ten minutes" long — but every single one of these is a real reference and we are not skipping a single one, bestie 😭

Kernel file ./kernel/sched/ext/ext.c:

ngl if you read all ninety-something of those in one sitting you deserve a little treat 🍓

and that's the page!! mwah 💋

so this one came out of ./kernel/sched/ext and it's dated October 2026 — put that in your notes app bestie, and go be a descendant of greatness 👑💜
