💅 kernfs_next_descendant_post(9) — NAME ✨

okay so bestie, welcome to the Kernel API Manual entry for kernfs_next_descendant_post 💖 and what it does is: find the next descendant for post-order walk 🦋 that's the whole vibe, that's the assignment, no cap.

🌸 SYNOPSIS 🌸

struct kernfs_node * kernfs_next_descendant_post (struct kernfs_node
*pos , struct kernfs_node *root );

like literally just those two args, iykyk 🫶

🎀 ARGUMENTS 🎀

  • pos — the current position, aka where you're at right now 💅 and yes, NULL to initiate traversal — that's your "start me up" moment, main character energy fr.
  • root — the kernfs_node whose descendants we're walking 🌈 this is the tree we're touring, bestie.

⭐ DESCRIPTION ⭐

So here's the tea ☕ — you call this to find the next descendant to visit for post-order traversal of root's descendants 🧚 and the important lore is this: root is included in the iteration and the last node to be visited 👑 like it's not just the venue, it's also the final guest of honor, periodt.

💜 RETURN 💜

it hands you back the next descendant to visit, or NULL when done 💀 — that NULL is your little "we're so done here" signal, bestie, respect it 🙈

🦋 SEE ALSO 🦋

Kernel file ./fs/kernfs/dir.c 😭 (yes the whole squad lives there) and the extended friend group:

go read them all, they ate 🔥

and that's the whole page bestie 🎀✨ this lil masterpiece came from ./fs/kernfs and it's dated October 2026 🗓️💖 so go forth and traverse your descendants in post-order, you absolute icon 👑💅 mwah 🫶
