💖 nilfs_palloc_freev(9) — Kernel API Manual bestie 💖

okay so this is the page for nilfs_palloc_freev(9), straight out of the Kernel API Manual. No gatekeeping, we’re learning this together. 🫶

🌸 NAME 🌸

nilfs_palloc_freev — deallocate a set of persistent objects. That’s the mission, bestie: deallocate a set of persistent objects. 💅

✨ SYNOPSIS ✨

int nilfs_palloc_freev (struct inode *inode , __u64 *entry_nrs , size_t
       nitems );

🎀 ARGUMENTS 🎀

• inode — inode of metadata file using this allocator. Like, this is the inode of the metadata file that’s using this allocator, okay? 🧚
• entry_nrs — array of entry numbers to be deallocated. It’s the lineup of entry numbers getting deallocated, no cap. 🦋
• nitems — number of entries stored in entry_nrs. Literally how many entries are stored in entry_nrs — the count, the amount, the whole tally. ✨

🔥 RETURN 🔥

0 on success, or a negative error code on failure. So: success = 0, failure = a negative error code. Check it, bestie, don’t just vibe and ignore the return value. 😭
