cgroup_taskset_next(9)

🎀 cgroup_taskset_next 💅

okay so this is a page straight out of the Kernel API Manual, section 9, and bestie it is tiny but it is important. let's get into it 🦋

---

✨ NAME ✨

cgroup_taskset_next — iterate to the next task in taskset 🌈

---

🫶 SYNOPSIS ✨

struct task_struct * cgroup_taskset_next (struct cgroup_taskset *tset ,
struct cgroup_subsys_state **dst_cssp );

like, that's the whole signature, no cap 💖

---

🌸 ARGUMENTS 🌸

• tset — the taskset of interest, aka the one you're snooping through 👀
• dst_cssp — output variable for the destination css, so it gets filled in for you 🎀

---

💜 DESCRIPTION 💜

Return the next task in tset. simple as that, fr fr.

⚠️ but listen — iteration must have been initialized with cgroup_taskset_first first. like, you can't just jump in mid-walk, that's not the vibe. start at the beginning, bestie. 🚨
