nilfs_palloc...bitmap_block(9)

Hey bestie 💖 welcome to the nilfs_palloc...bitmap_block(9) page from the Kernel API Manual. We’re doing a lil’ deep dive into nilfs_palloc_delete_bitmap_block, and honestly? It’s giving “small function, big allocator energy.” ✨

🌸 NAME 🌸

nilfs_palloc_delete_bitmap_block — delete a bitmap block 🗑️✨

🎀 SYNOPSIS 🎀

int nilfs_palloc_delete_bitmap_block (struct inode *inode , unsigned long group );

💅 ARGUMENTS 💅

Okay so here’s what you’re feeding it, bestie:

• inode — inode of metadata file using this allocator 🧚
• group — group number 🔢

🫶 RETURN 🫶

It returns 0 on success, or a negative error code on failure. That’s the whole mood: success is 0, failure is negative. 💀
