ibmvscsi_set_request_limit(9)

💅 ibmvscsi_set_request_limit 💅

okay so bestie, welcome to the ibmvscsi_set_request_limit(9) page from the Kernel API Manual ✨ — this is the little function that sets the adapter's request_limit when the adapter's having a Moment (failure, reset, or SRP Login) 🫶

---

✨ NAME ✨

ibmvscsi_set_request_limit — sets the adapter request_limit in response to an adapter failure, a reset, or an SRP Login 💖 and the whole thing runs under host lock, specifically so it doesn't race with SCSI command submission. no cap, that lock is the main character here 👑

---

🦋 SYNOPSIS 🦋

void ibmvscsi_set_request_limit (struct ibmvscsi_host_data *hostdata ,
int limit );

it returns void btw — nothing comes back, it just does the thing 💅

---

🎀 ARGUMENTS 🎀

• hostdata — the adapter you're adjusting, like, the whole point 🧚
• limit — the brand new request limit, the fresh number, the glow-up ⭐

lowkey reminder: this thing touches request_limit and it does it under host lock — that's not decoration, that's the whole reason it's safe against SCSI command submission racing in. respect the lock 🙈
