aa_dfa_free_kref(9)

✨ NAME ✨

okay so bestie, this is the aa_dfa_free_kref page from the Kernel API Manual, section 9 — and it does exactly one thing: it frees an aa_dfa by kref, and it gets called by aa_put_dfa. that's the whole vibe. clean, focused, main character energy 🎀

🌸 SYNOPSIS 🌸

void aa_dfa_free_kref (struct kref *kref );

literally one function, one pointer, zero drama. love that for us 💅

🦋 ARGUMENTS 🦋

• kref — the kref callback that does the freeing of a dfa, and she is NOT NULL 🚨 like, do not pass her a null, that's not the move. this is the handle that tells the kernel "okay this dfa is donezo, clean her up." keep it valid, keep it happy 🫶

ngl this one is short and sweet — no options, no environment variables, no exit statuses, no warnings, no bug notes, no examples. just a kref free callback being iconic and knowing her place 👑

that's the whole page, bestie — you ate that read-through 🌈
