🌸 SYNOPSIS

void vdo_prepare_completion_for_requeue (struct vdo_completion

🎀 ARGUMENTS

so here's the tea — the original page literally gives us nothing on these bad boys, so I'm not gonna make stuff up (that would be a vibe check fail 🙈):

• completion — -- undescribed -- 😭
• callback — -- undescribed --
• error_handler — -- undescribed --
• callback_thread_id — -- undescribed --
• parent — -- undescribed --

fr fr, all five are marked -- undescribed -- in the source. we simply don't know more than that. don't come for me 💀

✨ DESCRIPTION

the whole serve here is simple and honestly kinda slay:

it resets the completion, and then it sets its callback, its error handler, its callback thread, and its parent. that's the tea, that's the whole thing. 🍓

so like — reset first, assign second. main character energy all the way through. 👑
