nfs_page_create_from_folio(9)

🌈 NAME 🌈

nfs_page_create_from_folio(9) — create an NFS read/write request. Bestie, it's giving request-creation energy. ✨

Okay so this is the nfs_page_create_from_folio(9) page from the Kernel API Manual. Let's get into it, iykyk. 💖

🦋 SYNOPSIS 🦋

struct nfs_page * nfs_page_create_from_folio (struct nfs_open_context
       *ctx , struct folio *folio , unsigned int offset , unsigned int count );

🎀 ARGUMENTS 🎀

• ctx — open context to use. Your context, your vibe.
• folio — folio to write. Yes, that folio.
• offset — starting offset within the folio for the write. Precision, periodt.
• count — number of bytes to read/write. How many bytes we're moving.

💅 DESCRIPTION 💅

The page must be locked by the caller. This makes sure we never create two different requests for the same page. No duplicates, no chaos, we love to see it. 💅

User should ensure it is safe to sleep in this function. Like, check that before you snooze, bestie. 😭
