binder_free_buf(9)

💖 NAME 💖

binder_free_buf — free the specified buffer. Okay bestie, this is a Kernel API Manual page for section 9, and the whole assignment is literally right there in the name: free the specified buffer. No cap. ✨

✨ SYNOPSIS ✨

       void binder_free_buf (struct binder_proc *proc , struct binder_thread
       *thread , struct binder_buffer *buffer , bool is_failure );

🌸 ARGUMENTS 🌸

• proc — the binder proc that owns the buffer. She's the owner-owner. 💅
• thread — the binder thread performing the buffer release. Main character doing the release. 🫶
• buffer — the buffer to be freed. That's the target, bestie. 🎯
• is_failure — failed to send transaction. Yep, that's the failure situation. 😭

🦋 DESCRIPTION 🦋

If the buffer is for an async transaction, enqueue the next async transaction from the node. That's the async handoff, no cap. 🌈

Then cleanup the buffer and free it. That's literally the whole plot: cleanup, free, done. 💖
