💖 bio_chain_and_submit(9) 💖

okay bestie, so we're in the Kernel API Manual today and this page is about one little function that does a lot of quiet heavy lifting. it's giving "small but iconic". let's get into it ✨

🌸 NAME 🌸

bio_chain_and_submit — literally what it says on the tin: you submit a bio after you chain it onto another one. chain first, submit second, no cap 🫶

🎀 SYNOPSIS 🎀

struct bio * bio_chain_and_submit (struct bio *prev , struct bio *new );

🦋 ARGUMENTS 🦋

  • prev — the bio you're gonna chain and submit. yes, it's doing both jobs, main character energy fr 💅
  • new — the bio that prev gets chained onto. it's the one being chained to, iykyk

⭐ DESCRIPTION ⭐

so here's the whole tea: if prev is non-NULL, you chain it to new and then submit it. that's it. that's the function. lowkey elegant, highkey useful 🌈

and if prev is NULL? then there's nothing to chain and nothing getting submitted here — the condition is doing all the work, so pay attention to it 👑

🔥 RETURN 🔥

returns new. just new. that's the whole return value, bestie — it hands you back the bio you passed in as new 💜

👑 SEE ALSO 👑

and now the friend group 😭 — the kernel file ./block/bio.c is where this whole squad lives, and here's everyone:

ngl, that's a long guest list, but every single one of them earned their invite 💀 go read bio_chain(9) next if you wanna see the chaining part on its own — it's the prequel 🧚

and that's the whole page!! this little darling comes to you from the source ./block, dated October 2026 — mwah, sending you off with a kiss and a struct bio * 🍓💖✨
