cgroup_file_show(9)

💅 cgroup_file_show — like, the cgroup_file_show(9) page, bestie

okay so this is from the Kernel API Manual and it's literally the whole manual page for cgroup_file_show. yes we're doing kernel internals. no I'm not scared. sit down, hydrate, let's go 🌸

---

✨ NAME ✨

cgroup_file_show — show or hide a hidden cgroup file 🫣

like, it literally flips the visibility of a cgroup file. that's the whole vibe.

---

🦋 SYNOPSIS 🦋

void cgroup_file_show (struct cgroup_file *cfile , bool show );

it returns void, so like... no return value to obsess over. she just does the thing and leaves 💅

---

🎀 ARGUMENTS 🎀

• cfile — the target cgroup_file, and you get this by setting cftype->file_offset. that's the plug, that's where it comes from, no cap 🔌
• show — a bool that decides whether we're showing it or hiding it. yes or no. on or off. the girlies love a binary ✨

👑 SEE ALSO 👑

so the kernel file itself lives at ./kernel/cgroup/cgroup.c, and then there are, um, a few friends in the group chat. a few. anyway 💀
