netfs_release_folio(9)

✨ netfs_release_folio ✨

okay so bestie, welcome to the netfs_release_folio(9) page from the Kernel API Manual 💅 this one's short and sweet and honestly kinda iconic for it.

🌸 NAME 🌸

netfs_release_folio — the "can we please let this folio go" check 🎀

🦋 SYNOPSIS 🦋

bool netfs_release_folio (struct folio *folio , gfp_t gfp );

💖 ARGUMENTS 💖

• folio — the folio that's being proposed for release, aka the main character of this whole function 👑
• gfp — the flags that qualify the release, iykyk 🌈

⭐ DESCRIPTION ⭐

So what it does: it requests release of a folio and cleans up that folio's private state — but only if it's not busy. no cap, if it's busy, it just doesn't.

It returns true if the folio can now be released, and false if it can't. that's the whole vibe check 🫶
