💅 cpuset_css_alloc(9) — like, the Kernel API Manual one 🎀

okay so bestie, welcome to the cpuset css allocation party ✨ this is a Kernel API Manual page, so buckle up, we're in kernel-land now 🦋

✨ NAME ✨

cpuset_css_alloc — allocate a cpuset css 🫶 (yes that's the whole name, she's lowkey self-explanatory and we love that for her)

🌸 SYNOPSIS 🌸

struct cgroup_subsys_state * cpuset_css_alloc (struct
cgroup_subsys_state *parent_css );

like, she takes one thing and hands you a struct cgroup_subsys_state * back, no cap 💫

🎀 ARGUMENTS 🎀

  • parent_css — the parent css of the control group that the new cpuset is gonna be part of 🧚 so like, your new cpuset is joining that family, iykyk

👑 RETURN 👑

  • the cpuset css on success 🎉 slay
  • -ENOMEM on failure 😭 (out of memory, tragic, we've all been there)

🔥 DESCRIPTION 🔥

so what she does is allocate and initialize a brand new cpuset css 💅 and here's the tea: for a non-NULL parent_css, you get that freshly allocated cpuset css. but if parent_css is NULL, she returns the top cpuset css instead 👀 main character energy fr fr.
