ntb_transport_link_down(9)

💖 NAME 💖

ntb_transport_link_down — notify NTB transport to no longer enqueue data, bestie 🎀

This is the ntb_transport_link_down(9) page from the Kernel API Manual, and yes, we are getting into it ✨

✨ SYNOPSIS ✨

void ntb_transport_link_down (struct ntb_transport_qp *qp );

🎀 ARGUMENTS 🎀

• qp — the NTB transport layer queue to be disabled. That's the queue getting the “no more data for you” treatment 💅

🦋 DESCRIPTION 🦋

okay so this one notifies the NTB transport layer of the client's desire to no longer receive data on the transport queue specified. It's giving “we're closed for business on this queue” ✨

and bestie, listen: it is the client's responsibility to ensure all entries on queue are purged or otherwise handled appropriately. No cap, handle your cleanup 🧹💀
