xprt_retry_reserve(9)

💖 NAME 💖

okay so welcome to the Kernel API Manual entry for xprt_retry_reserve — she allocates an RPC request slot, and she does it with main character energy 👑

• xprt_retry_reserve — allocate an RPC request slot

---

✨ SYNOPSIS ✨

the signature is literally right here, untouched, because we do not play with source code 💅:

void xprt_retry_reserve (struct rpc_task *task );

---

🎀 ARGUMENTS 🎀

• task — RPC task requesting a slot allocation. she's the one asking for space, bestie 🫶

---

🦋 DESCRIPTION 🦋

bestie, here's the tea: if no more slots are available, place the task on the transport's backlog queue. that's the move ✨

and note — the only difference with xprt_reserve is that we now ignore the value of the XPRT_CONGESTED flag. no cap, that's the whole distinction 💅
