scx_prog_sched(9)

okay bestie, welcome to scx_prog_sched(9) from the Kernel API Manual — section 9, no cap. it’s giving kernel-internals realness, and we’re gonna get you comfy with it. 💅✨

🌸 NAME 🌸

scx_prog_sched — find the scx_sched associated with a BPF prog. periodt. 🎀

✨ SYNOPSIS ✨

here’s the vibe in C, exactly as it is:

struct scx_sched * scx_prog_sched (const struct bpf_prog_aux *aux );

🫶 ARGUMENTS 🫶

• aux — the aux passed in from BPF to a kfunc. yes bestie, that’s the whole argument. iconic minimalism. 💖

💅 DESCRIPTION 💅

okay so this one is to be called from kfuncs. it returns the scheduler instance associated with the BPF program, given the implicit kfunc argument aux. the returned scx_sched is RCU protected — noted, bestie, don’t forget that part. 🔥
