STRUCT LIVEUPDATE_FLB(9)

🌸 NAME 🌸

struct liveupdate_flb — a global definition for a shared data object. Yep bestie, we’re in the Kernel API Manual for struct liveupdate_flb(9), and this is the whole vibe. 💅

✨ SYNOPSIS ✨

struct liveupdate_flb {
    const struct liveupdate_flb_ops *ops;
    const char compatible[LIVEUPDATE_FLB_COMPAT_LENGTH];
};

🎀 Members 🎀

• ops — callback functions. That’s the whole description, no cap. 🫶
• compatible — the compatibility string (e.g., "iommu-core-v1") that uniquely identifies the FLB type this handler supports. This is matched against the compatible string associated with individual struct liveupdate_flb instances. 💖

💖 Description 💖

This struct is the “template” that a driver registers to define a shared, file-lifecycle-bound object. The actual runtime state — the live object, refcount, etc. — is managed privately by the LUO core. So the driver brings the template, and the LUO core handles the backstage situation, periodt. ✨
