nilfs_pallo..._alloc_entry(9)

💅 NAME

Okay bestie, gather round, because this one is nilfs_palloc_commit_alloc_entry — the function that finishes allocation of a persistent object. That's it, that's the whole job: the allocation was doing its little warm-up, and this is the glow-up that makes it official. ✨

And for the record, this page is living in the Kernel API Manual, section 9, under the title nilfs_pallo..._alloc_entry(9) (yes, the title is truncated with dots, no that's not a typo, that's just how it's filed, iykyk). 🎀

✨ SYNOPSIS

void nilfs_palloc_commit_alloc_entry (struct inode *inode , struct
     nilfs_palloc_req *req );

Returns nothing. It just does the thing. No cap. 💅

🌸 ARGUMENTS

• inode — the inode of the metadata file that's using this allocator. Like, this is the file whose little bookkeeping brain is running the whole show. 🧠
• req — the nilfs_palloc_req structure that got exchanged for the allocation. This is the receipt, basically. Hand it over and the allocation is locked in. 🧾

Lowkey obsessed with how nilfs_palloc_prepare_alloc_entry(9) sets it up and nilfs_palloc_commit_alloc_entry is the one who actually seals the deal. The abort version is right there too if things go sideways. Teamwork, honestly. 🫶

And that's a wrap, bestie! 🎀 This iconic little page comes to you from ./fs/nilfs2, dated October 2026, and it's filed under the Kernel API Manual, section 9 — nilfs_pallo..._alloc_entry(9) forever and always. Go forth and commit those allocations. 💖🌈⭐
