rdma_rw_ctx_destroy_bvec(9)

💖 rdma_rw_ctx_destroy_bvec(9) — from the Kernel API Manual ✨

okay so bestie, this little function is the cleanup era of the RDMA lifecycle. Like, rdma_rw_ctx_init_bvec did all the hard work and got the main character energy, and now this one comes in quietly, cleans up the mess, and leaves. Respect. 🫶

🌸 NAME 🌸

rdma_rw_ctx_destroy_bvec — the one that releases resources from rdma_rw_ctx_init_bvec 🎀

---

✨ SYNOPSIS ✨

void rdma_rw_ctx_destroy_bvec (struct rdma_rw_ctx *ctx , struct ib_qp
*qp , u32 port_num , const struct bio_vec *bvecs , u32 nr_bvec , enum
dma_data_direction dir );

like, yes, that's the whole signature. six params. she's thorough 💅

---

🦋 ARGUMENTS 🦋

• ctx — the context you're releasing, bestie. the thing being set free. 🕊️
• qp — the queue pair we're operating on. the actual main character here.
• port_num — the port num the connection is bound to… and it's unused, so ngl it's just there for the vibes ✨ (API symmetry, we'll get to that)
• bvecs — the bio_vec array that was used for the READ/WRITE. also unused. iconic of her to show up and do nothing 💀
• nr_bvec — number of entries in bvecs. this one actually matters, lowkey.
• dir — direction of the transfer: DMA_TO_DEVICE for RDMA WRITE, DMA_FROM_DEVICE for RDMA READ. pick the right one, fr fr 🔥

🎀 DESCRIPTION 🎀

So here's the tea: this function releases all resources allocated by a successful rdma_rw_ctx_init_bvec call. every single one. she's not leaving anything behind, periodt. 🧹✨

⚠️ BIG WARNING, bestie, do not skip this: you must not call this if rdma_rw_ctx_init_bvec returned an error. like, nope. that's not the vibe. clean up is only for the successful ones 😭🙈

And about the two freeloaders — the port_num and bvecs parameters are unused, but they're present for API symmetry with rdma_rw_ctx_destroy. so they're not bugs, they're aesthetic. balance. symmetry. it's giving choreography 🩰💜
