ext2_free_data(9)

💖 NAME 💖

Okay bestie, welcome to ext2_free_data(9) from the Kernel API Manual — this one is literally about freeing a list of data blocks ✨

🌸 SYNOPSIS 🌸

void ext2_free_data (struct inode *inode , __le32 *p , __le32 *q );

🎀 ARGUMENTS 🎀

• inode — the inode we are dealing with, main character energy 👑
• p — array of block numbers, slay
• q — points immediately past the end of the array, iykyk

🦋 DESCRIPTION 🦋

So what’s the vibe? We are freeing all blocks referred from that array — and yes, the numbers are stored as little-endian 32-bit, no cap — and we’re updating inode->i_blocks appropriately 💅
