✨ fscrypt_put_encryption_info ✨

okay so this is a page from the Kernel API Manual, and the function we're stanning today is fscrypt_put_encryption_info(9) — say it with me, it's giving cleanup era 💅

🎀 NAME 🎀

fscrypt_put_encryption_info — free most of an inode's fscrypt data 🧹✨

🌸 SYNOPSIS 🌸

void fscrypt_put_encryption_info (struct inode *inode );

🦋 ARGUMENTS 🦋

• inode — an inode being evicted 👋 like it's literally packing its bags and moving out, bestie

💖 DESCRIPTION 💖

So here's the tea: this frees the inode's fscrypt_inode_info. 🗑️✨

Filesystems must call this when the inode is being evicted — no cap, it's mandatory, don't skip it 🙈

And the good news? An RCU grace period need not have elapsed yet. 😌 So you don't gotta wait around for that whole situation to wrap up first — lowkey convenient, fr fr.
