kernfs_show(9)

📦 version 7.3.1, in nixpkgs unstable

💅 kernfs_show — show or hide a node ✨

okay so bestie, welcome to kernfs_show(9), a page from the Kernel API Manual, and honestly? it's a little icon of a function. let's get into it 🫶

🌸 SYNOPSIS 🌸

void kernfs_show (struct kernfs_node *kn , bool show );

that's it. that's the whole vibe. two args, void return, no notes 💅

🎀 ARGUMENTS 🎀

  • kn — the kernfs_node you're gonna show or hide. this is the main character here, lowkey 👑
  • show — a bool that literally just says: are we showing it or hiding it? that's the whole decision, no cap

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓

if show is false, then kn gets marked hidden and deactivated. and a hidden node? it gets ignored in future activaitons — yes that's how it's spelled in the original, i'm keeping it, character for character, iykyk 😭✨

if show is true, then the mark is removed and the activation state is restored. slay, we love a comeback 💖

but listen — this function won't implicitly activate a new node in a KERNFS_ROOT_CREATE_DEACTIVATED root that hasn't been activated yet. so don't come for this function expecting it to do that, because it simply will not 🙈

and one more thing, no cap: to avoid recursion complexities, directories aren't supported for now. that's right, directories are not invited to this party. periodt 💀

🌈 SEE ALSO 🌈

the kernel file ./fs/kernfs/dir.c and honestly a whole friend group of functions — every single one of them, right here, no skips:

like, the whole squad. go read them, bestie, they're all waiting 🧚

⭐ sign-off ⭐

this little beauty lives in ./fs/kernfs, dated October 2026, and it's filed under kernfs_show(9) in the Kernel API Manual. that's the whole page, mwah 💜🎀
