rtrs_clt_get_permit(9)

💖 NAME 💖

rtrs_clt_get_permit — allocates permit for future RDMA operation. That's the whole vibe: it gets you a permit for what's coming next, bestie 🎟️✨

This page is from the Kernel API Manual, and it's literally all about getting that permit sorted before the RDMA operation shows up 💅

---

✨ SYNOPSIS ✨

struct rtrs_permit * rtrs_clt_get_permit (struct rtrs_clt_sess *clt ,
enum rtrs_clt_con_type con_type , enum wait_type can_wait );

---

🎀 ARGUMENTS 🎀

• clt — the current session, aka your main character session 💅
• con_type — type of connection to use with the permit 🔌
• can_wait — wait type ⏳

---

🌸 DESCRIPTION 🌸

So rtrs_clt_get_permit allocates permit for the following RDMA operation. The permit is there to preallocate all resources and to propagate memory pressure up earlier — it's giving prepared-bestie energy 💖✨ No scrambling later, iykyk.

---

🦋 CONTEXT 🦋

Context check: it can sleep if wait == RTRS_PERMIT_WAIT 😴🫶 That's the tea.
