rvt_free_qpn(9)

🎀 rvt_free_qpn(9) 🎀

Hey bestie!! Welcome to the rvt_free_qpn(9) page from the Kernel API Manual — it's giving tiny-but-iconic cleanup-function energy, and honestly? Obsessed 💅✨

🌸 NAME 🌸

rvt_free_qpn — frees a qpn from the bit map. That's it, that's the whole main-character moment: one qpn gets freed from the bit map, and we love a clean exit 💖

🌈 SYNOPSIS 🌈

Here's the exact signature, copy-paste bestie:

void rvt_free_qpn (struct rvt_qpn_table *qpt , u32 qpn );

🦋 ARGUMENTS 🦋

• qpt — QP table. The table itself, bestie 🌟
• qpn — queue pair number to free. Say bye to that qpn 👋🫶
