STRUCT FSL_MC_RESOURCE(9)

💖 struct fsl_mc_resource — MC generic resource 💖

okay so bestie, welcome to the Kernel API Manual page for struct fsl_mc_resource, aka the little generic-resource baddie that lives in ./include/linux/fsl. it's giving "humble struct, big responsibilities" and honestly? we stan. 🎀

---

✨ SYNOPSIS ✨

struct fsl_mc_resource {
    enum fsl_mc_pool_type type;
    s32 id;
    void *data;
    struct fsl_mc_resource_pool *parent_pool;
    struct list_head node;
};

look at her. five fields. zero notes. absolute main character energy. 👑

🦋 Members 🦋

• type — the type of resource. literally just… what kind of resource this is. vibe check passed. ✨
• id — the unique MC resource Id within the resources of the same type. so like, id is only unique against its own type-siblings, not against everybody — iykyk. 🫶
• data — a pointer to resource-specific data if the resource is currently allocated, or NULL if the resource is not currently allocated. so if you deref this without checking, that's on you bestie 😭 check for NULL first, fr fr.
• parent_pool — pointer to the parent resource pool that this resource is allocated from. every resource has a mom, and her name is parent_pool. 💅
• node — the node in the free list of the corresponding resource pool. it's on the list, it's chilling, it's waiting for its turn. 🌸

⭐ NOTE ⭐

this structure is meant to be embedded as a field of specific MC resource structures. not a standalone diva — she's a supporting cast member, and she plays that role iconically. 🎬

lowkey important: embed her, don't malloc her separately. that's the whole point, no cap. 🔥
