✨ NAME ✨

/proc/pid/cpuset — CPU affinity sets 💅

yes bestie, that's the whole NAME section. she's concise. she ate and left no crumbs.

🌸 DESCRIPTION 🌸

• /proc/pid/cpuset (since Linux 2.6.12) — okay so this is the per-process cpuset file, and honestly? the manpage does NOT gatekeep the details here, it just points you straight at the real one:

See cpuset(7).

periodt. that's it. that's the description. if you wanna actually understand cpuset behavior, all the juicy lore lives over in cpuset(7), so go read her, she's iconic 👑

ngl, this is giving "short king" energy — lowkey tiny page, highkey important file. iykyk 💀
