✨ nilfs_palloc_prepare_free_entry — Kernel API Manual energy ✨

okay so bestie, welcome to the Kernel API Manual corner of the internet 💅 this one's a little function from the nilfs2 allocator and honestly? it's giving "getting your ducks in a row before the actual ducks get deleted." let's go 🦋

💖 NAME 💖

nilfs_palloc_prepare_free_entry — prepare to deallocate a persistent object 🎀

like, it's the prep step. the "let me get ready first" step. the main character energy before the main character shows up ✨

🌸 SYNOPSIS 🌸

int nilfs_palloc_prepare_free_entry (struct inode *inode , struct
nilfs_palloc_req *req );

🦋 ARGUMENTS 🦋

  • inode — the inode of the metadata file that's using this allocator, iykyk 🫶 this is who's in charge of the block-groups situation.
  • req — the nilfs_palloc_req structure that gets exchanged for the removal 👀 so it's the little request envelope you hand over, and it comes back all set up for the freeing.

⭐ RETURN ⭐

returns 0 on success 🎉 or a negative error code on failure 😭 (yes, negative — kernel functions are like that, don't @ me).

🔥 SEE ALSO 🔥

bestie note: if you're actually in the kernel and you skip the prepare → commit / abort pipeline, that's not slay, that's a bug 🙈 read the friends above before you touch anything, periodt.

cute sign-off time 🎀 this little beauty comes from ./fs/nilfs2 and the date on it is October 2026 — yes, future energy, we love to see it ⭐ mwah, go free some persistent objects responsibly 💅✨
