nfs_iocounter_wait(9)

✨ NAME ✨

okay bestie, meet nfs_iocounter_wait(9) from the Kernel API Manual 💖 — it's literally the “wait for i/o to complete” function. That's the vibe.

💅 SYNOPSIS 💅

int nfs_iocounter_wait (struct nfs_lock_context *l_ctx );

🫶 ARGUMENTS 🫶

• l_ctx — the nfs_lock_context with the io_counter to use 🌸. That's the one, no cap.

🔥 DESCRIPTION 🔥

So here's the tea: it returns -ERESTARTSYS if it gets interrupted by a fatal signal 😭. Otherwise, it returns 0 once the io_count hits 0 — periodt. ✨
