STRUCT I2C_ATR_ALIAS_POOL(9)

🦋 NAME 🦋

struct i2c_atr_alias_pool — bestie, it's literally the pool of client aliases available for an ATR 💅 (this is from the kernel API manual, iykyk)

✨ SYNOPSIS ✨

okay so here's the whole struct, no cap, copied exactly:

struct i2c_atr_alias_pool {
    size_t size;
    bool shared;
    spinlock_t lock;
    unsigned long *use_mask;
    u16 aliases[];
 };

🎀 Members 🎀

the way that every single field has a job and ate:

• size — total number of aliases, like the headcount of the whole pool 🫶
• shared — tells you if this alias pool is shared by multiple channels (yes bestie, it's a group chat situation)
• lock — the lock protecting aliases and use_mask, main character energy keeping everybody safe 🔥
• use_mask — mask of used aliases, so you know who's already taken 👀
• aliases — array of aliases, and it must hold exactly size elements — like, exactly, not "around" size, not "size plus vibes", exactly bestie 💀
