irdma_rem_ref_cm_node(9)

🎀 NAME 🎀

okay so bestie, gather round: irdma_rem_ref_cm_node — destroy an instance of a cm node. that's the whole pitch. it's giving cleanup era, it's giving "we're done here, goodbye little node". this one lives in the Kernel API Manual, section 9, and it is so short and sweet, we love a low-maintenance queen 💅

✨ SYNOPSIS ✨

void irdma_rem_ref_cm_node (struct irdma_cm_node *cm_node );

returns void, no fancy return value, no drama, no notes. she simply does the thing and leaves 🌸

🦋 ARGUMENTS 🦋

• cm_node — connection's node. that's the entire description the page gives us and honestly? iconic brevity. it's the node belonging to the connection, and it's the one getting destroyed. periodt 🫶
