ib_dealloc_pd(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ib_dealloc_pd — the kernel API manual, section 9, bestie 💅

okay so real talk, this one's a lil page from the kernel API manual (that's section 9, iykyk) and it's all about saying bye-bye to a kernel PD. short page, iconic behavior, let's go 🎀

✨ NAME ✨

ib_dealloc_pd — literally deallocates a kernel PD. that's it. that's the whole vibe check 🦋

🌸 SYNOPSIS 🌸

void ib_dealloc_pd (struct ib_pd *pd );

no cap, that's the entire signature. returns nothing, takes one thing. clean. minimal. ate. 👑

💖 ARGUMENTS 💖

  • pd — the protection domain. yes that protection domain. the one you're sending off into the void 🫶

🎀 NOTE 🎀

okay bestie this is the important part, listen up 🙈

for user PD use ib_dealloc_pd_user with valid udata!

like. if it's a user PD you do not come through here, you go to ib_dealloc_pd_user and you bring a valid udata with you. no valid udata? no. do not pass go. do not collect $200. 💀

🌈 SEE ALSO 🌈

and that's the page!! tysm for reading, mwah 🫶 this one lives in ./include/rdma and it's dated October 2026, so yeah — see you in the future bestie, stay deallocated 💜🧚‍♀️
