auditd_conn_free(9)

💖 auditd_conn_free(9) — the Kernel API Manual page your bestie has been waiting for

okay so this is auditd_conn_free, straight out of the Kernel API Manual, section 9. it's a tiny little function but she is literally doing the cleanup work nobody wants to do, and honestly? main character energy. 🧹✨

🌸 NAME

auditd_conn_free — an RCU helper that releases an auditd connection struct 🫶

🎀 SYNOPSIS

void auditd_conn_free (struct rcu_head *rcu );

🦋 ARGUMENTS

• rcu — the RCU head 💅 (that's it, that's the whole argument, she's low maintenance)

✨ DESCRIPTION

so what it does is: it drops any references that are hanging out inside the auditd connection tracking struct, and then it frees the memory. 🗑️💖

like, references gone, memory freed, closure achieved. no cap.

ngl it's a small function, but it's the kind of small function that keeps the whole audit subsystem from leaking everywhere. respect her. 👑
