irdma_prep_remove_sd_bp(9)

💅 irdma_prep_remove_sd_bp — a Kernel API Manual moment 🎀

okay bestie, so this is a page from the Kernel API Manual (section 9, the kernel dev girly section, iykyk) and it's all about irdma_prep_remove_sd_bp ✨

---

🌸 NAME 🌸

irdma_prep_remove_sd_bp — literally just prepares to remove a backing page from a sd entry. that's it. that's the whole vibe. it does the prep work, not the removal itself — think of it as the getting-ready-with-me portion of the operation 🫶

---

💖 SYNOPSIS 💖

int irdma_prep_remove_sd_bp (struct irdma_hmc_info *hmc_info , u32 idx
);

so it hands you back an int, and it takes exactly two things. no more, no less. slay 💅

---

🦋 ARGUMENTS 🦋

• hmc_info — pointer to the HMC configuration information structure. yes king, give us that pointer to the config info 👑
• idx — the page index. which page? the page. this one. this index right here 🎀

💀 reminder bestie: this one only prepares to remove a backing page from a sd entry. it does not do the removing. don't be out here expecting full removal from the prep function, i'm begging 🙈
