STRUCT ASYNC_SUBMIT_CTL(9)

💖 NAME 💖

okay so bestie, you're on the Kernel API Manual page for struct async_submit_ctl(9) — the struct for async_tx submission/completion modifiers. no cap, it's the little vibe-check bundle for async tx stuff. 🦋

✨ SYNOPSIS ✨

struct async_submit_ctl {
           enum async_tx_flags flags;
           struct dma_async_tx_descriptor *depend_tx;
           dma_async_tx_callback cb_fn;
           void *cb_param;
           void *scribble;
        };

• flags — submission modifiers. that's the main-character switchboard, periodt. 💅
• depend_tx — parent dependency of the current operation being submitted. it's literally the "wait for your parent" link, iykyk. 🔗
• cb_fn — callback routine to run at operation completion. the little celebration function when the op is done. 🎀
• cb_param — parameter for the callback routine. the snack you pass to cb_fn. 🍓
• scribble — caller provided space for dma/page address conversions. your own lil scratch zone, no borrowing. ✨
