okay so welcome to the Kernel API Manual page for __label_find_merge, and it's literally about finding a label that is equiv to merge of @a and @b. we're gonna keep every detail, no cap. 🫶

✨ NAME ✨

__label_find_merge — find label that is equiv to merge of @a and @b

🦋 SYNOPSIS 🦋

struct aa_label * __label_find_merge (struct aa_labelset *ls , struct
       aa_label *a , struct aa_label *b );

🌸 ARGUMENTS 🌸

okay bestie, here's the cast of characters:

• ls — set of labels to search (NOT NULL), like the whole friend group you're searching through.
• a — label to merge with b (NOT NULL).
• b — label to merge with a (NOT NULL).

🎀 DESCRIPTION 🎀

Requires: ls->lock read_lock held.

that's the whole prerequisite, bestie. ls->lock read_lock held, periodt. 💅

🔥 RETURN 🔥

you get a ref counted label that is equiv to merge of a and b, else NULL if merge of a and b is not in set. that's the return tea. 🍵
