trace_io_uring_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual ✨ today's main character is a tracepoint hook called trace_io_uring_link — she's the one who gets called right before an io_uring request gets added into the link_list of another request. literally the moment before the friendship bracelet gets tied 🎀

🌸 NAME

trace_io_uring_link — called before the io_uring request added into link_list of another request 🫶

✨ SYNOPSIS

void trace_io_uring_link (struct io_kiocb *req , struct io_kiocb *target_req );

🎀 ARGUMENTS

  • req — pointer to a linked request 💖 like, the one getting linked, bestie
  • target_req — pointer to a previous request, that would contain req 👑 she's the holder, the container, the one whose link_list is about to get a new member

🦋 DESCRIPTION

so what does she do? she lets you track linked requests 🌈 which means you get to actually understand the dependencies between requests — and how does it influence their execution flow. it's giving "let me show you the whole web of who-needs-who" 🔥 no cap, that's the entire vibe.
