nfs_wait_on_request(9)

🎀 NAME 🎀

nfs_wait_on_request — wait for a request to complete. okay so this is nfs_wait_on_request(9) from the Kernel API Manual, and it is literally giving “wait for a request to complete” energy. slay. ✨

---

✨ SYNOPSIS ✨

here’s the signature bestie, copy it exactly because we do not edit code in this house:

int nfs_wait_on_request (struct nfs_page *req );

---

🫶 ARGUMENTS 🫶

• req — the request to wait upon. that’s the one you’re waiting on, bestie. 💖

💅 DESCRIPTION 💅

okay so the wait is interruptible by fatal signals only — like, not your everyday interruption, only the fatal-signal girlies can break in. 💀

and the big rule: the user is responsible for holding a count on the request. no cap, hold that count. it’s literally your job. 🫡
