debugfs_leave_cancellation(9)

📦 version 7.3.1, in nixpkgs unstable

💅 debugfs_leave_cancellation — leave cancellation section 🎀

okay so bestie, this is a page from the Kernel API Manual (debugfs_leave_cancellation(9), section 9, kernel gang only) and it's honestly short and sweet — the way a good cleanup function SHOULD be. It's the "and we're done here, bye 👋" counterpart to entering a cancellation section. Let's get into it ✨

🌸 SYNOPSIS 🌸

void debugfs_leave_cancellation (struct file *file, struct debugfs_cancellation *cancellation);

It returns void, so like… no return value, no exit status, nothing to check. You just call it and vibe. 🫶

🦋 ARGUMENTS 🦋

  • file — the file being accessed. yep, that file. the one you're currently doing stuff with 👀
  • cancellation — the cancellation you previously registered with debugfs_enter_cancellation. it's the same one!! the matching one!! not a new one, bestie 😭
no cap: these two arguments are a matched set. you enter with debugfs_enter_cancellation, you leave with debugfs_leave_cancellation. iconic symmetry, honestly. 💅

✨ DESCRIPTION ✨

so the actual description here is literally just "see the documentation of debugfs_enter_cancellation" — like, the kernel devs said iykyk and pointed you at the other page. 📖

fr fr, that's the whole description. go read debugfs_enter_cancellation(9) and everything will make sense. this page is the sequel, not the origin story. 🎬

👑 SEE ALSO 👑

These all live in the kernel file ./fs/debugfs/file.c — here's the whole squad, no one left behind:

💖 that's the whole page, bestie. short, matched-pair, no drama. leave the cancellation section the way you entered it and everyone stays happy. periodt.

🍓 sign-off time 🍓 — this lil beauty comes from the source path ./fs/debugfs, dated October 2026, under the Kernel API Manual. she's official, she's kernel-coded, and she's out 💜🧚🌸
