debug_object_active_state(9)

💅 debug_object_active_state — debug checks object usage state machine ✨

okay so bestie, quick vibe check: this page is straight out of the Kernel API Manual, and it's all about that debug-objects life. debug_object_active_state is the little function that debug-checks the state machine of an object's usage. like, it's literally the bouncer at the club checking your wristband before you move to the next room 🎀

✨ SYNOPSIS ✨

void debug_object_active_state (void *addr , const struct
debug_obj_descr *descr , unsigned int expect , unsigned int next );

that's the whole signature, no cap. void return, four args, iconic behaviour 🫶

🌸 ARGUMENTS 🌸

• addr — the address of the object. yes, the actual object. point at it. 👉
• descr — pointer to an object-specific debug description structure (const struct debug_obj_descr *). it's the object's little ID card, if you will 💳
• expect — the expected state. what you think this object's state is right now, bestie. the vibe you're expecting. 🌈
• next — the state to move to if the expected state is found. so if expect checks out, we slide on over to next. it's giving level-up energy ⭐

🦋 SEE ALSO 🦋

like, go read the source, it's all right there in the kernel file ./lib/debugobjects.c, plus the whole sibling squad of debug object functions:

• debug_object_init(9)
• debug_object_init_on_stack(9)
• debug_object_activate(9)
• debug_object_deactivate(9)
• debug_object_destroy(9)
• debug_object_free(9)
• debug_object_assert_init(9)

all of them. every single one. iykyk 💜

so yeah, that's the page 💖 shoutout to the ./lib source and the October 2026 date it was stamped with — mwah, love that for us. now go forth and debug your objects, bestie, you're gonna slay 🔥👑
