like, the whole personality of this function is "hey, don't forget about this fence, bestie." that's it. that's the vibe.

🌸 SYNOPSIS 🌸

gfp_t flags );

it returns an int, and it takes three things. slay. 💅

🦋 ARGUMENTS 🦋

  • sync — the sync object you're adding the fence to. this is the home base, the main character of the operation 👑
  • f — the fence to sync to. this is the fence in question. the one we're remembering. say hi to it 🌈
  • flags — the memory allocation flags to use when allocating the sync entry. lowkey important, don't sleep on these 💜

✨ DESCRIPTION ✨

Add the fence to the sync object.

that's it. that's the whole description. the way this function does exactly one (1) thing and is fully unbothered about it? we stan a focused icon 💖

ngl, the original manpage keeps it very brief here, so there's genuinely nothing more to tell you — the entire documented behaviour is "add the fence to the sync object." no extra lore, no secret bonus behaviour, no cap. 🔥
