xdr_inline_pages(9)

💅 xdr_inline_pages(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is xdr_inline_pages, and honestly? she's the one who sets up the vibe before the big reply even shows up 👑

---

🌸 NAME 🌸

xdr_inline_pages — prep the receive buffer so a large reply has somewhere cute to land 🎀

---

✨ SYNOPSIS ✨

void xdr_inline_pages (struct xdr_buf *xdr , unsigned int offset ,
       struct page **pages , unsigned int base , unsigned int len );

no cap, that's the whole signature — she takes it and she returns void (iconic, unbothered, gives nothing back 💅).

---

🦋 ARGUMENTS 🦋

• xdr — the xdr_buf that's gonna get the reply dropped into it. the vessel. the destination. the moment. 💖
• offset — the expected offset (in bytes, always bytes) where the data payload kicks off. like, where the actual content starts. lowkey important 🫶
• pages — a vector of struct page pointers. yes, the whole squad, all lined up 🌈
• base — offset inside the first page where the receive should begin, measured in bytes. yes, in bytes. bestie the manpage says it twice for a reason 😭
• len — the expected size of the upper layer data payload, in bytes. that's how much room we're reserving for the queen's entrance 👑

ok that's the whole page bestie, no filler, no skipped sections, we ate and left zero crumbs 🍓
