gfp_t(9)

okay so bestie, welcome to gfp_t(9) from the Kernel API Manual — this is the page about memory allocation flags, and it's lowkey iconic for doing so much with one little typedef. ✨💅

🌸 NAME 🌸

typedef gfp_t — memory allocation flags, periodt. 🎀

✨ DESCRIPTION ✨

GFP flags are commonly used throughout Linux to indicate how memory should be allocated. That's the whole vibe: they're the little signals that tell the kernel what kind of memory situation it's in. 🧚✨

The GFP acronym stands for get_free_pages, which is the underlying memory allocation function. No cap, that's literally what it means. 💖

Not every GFP flag is supported by every function which may allocate memory — so yeah, bestie, don't just assume every flag works everywhere. 🙈

Most users will want to use a plain GFP_KERNEL — that's the main character move for most people. 👑💅
