ext2_free_blocks(9)

💅 ext2_free_blocks(9) 💅

okay so this is the Kernel API Manual entry for ext2_free_blocks, and bestie it's giving “short king of block freeing.” no cap. It frees blocks and handles the quota + i_blocks glow-up. let's go. ✨

🌸 NAME 🌸

ext2_free_blocks — the NAME line has that little - - quirk, and the actual fact is: Free given blocks and update quota and i_blocks. periodt. 💖

✨ SYNOPSIS ✨

literal signature, copied exactly so you don't have to squint:

void ext2_free_blocks (struct inode * inode , ext2_fsblk_t block ,
       unsigned long count );

🎀 ARGUMENTS 🎀

okay the cast list is short and iconic:

• inode — the inode. that's the whole description, and honestly? minimalism ate. 💅
• block — the start physical block to free. that's the one you're pointing at first, bestie. 🫶
• count — the number of blocks to free. yes, plural, we're doing a little block-clearing spree. 🔥

no DESCRIPTION section here, bestie — this page is lowkey just the essentials, and that's valid. 😌
