worker_pool_assign_id(9)

📦 version 7.3.1, in nixpkgs unstable

💅 worker_pool_assign_id — from the Kernel API Manual, section 9, bestie

okay so picture this: you're deep in the kernel, section 9 of the Kernel API Manual, page worker_pool_assign_id(9), and you just need a pool to have an ID. that's it. that's the whole gig. and honestly? iconic of it. 🎀

✨ NAME ✨

worker_pool_assign_id — allocate an ID and assign it to @pool, no cap 💖

✨ SYNOPSIS ✨

int worker_pool_assign_id (struct worker_pool *pool );

(yes the space before the ) lives there rent-free, we don't touch it, we respect it 🫶)

✨ ARGUMENTS ✨

  • pool — the pool pointer of interest, aka the main character of this whole operation 💅

🌸 DESCRIPTION 🌸

okay so here's the vibe check: this function returns 0 if an ID in the range [0, WORK_OFFQ_POOL_NONE) gets allocated and assigned to your pool successfully. slay, ID delivered. ✨

and if it doesn't work out? it hits you with -errno on failure. not the happy path, but at least it tells you why 😭

lowkey a whole range check AND an allocation in one call?? the multitasking. the range [0, WORK_OFFQ_POOL_NONE) is doing so much heavy lifting and nobody's talking about it fr fr.
