fr fr the description slot is literally empty, that's not me being lazy, that's the page. so the name is the whole vibe check here 🎀

🌈 SYNOPSIS 🌈

void ecryptfs_kill_block_super (struct super_block *sb );

look at that signature, no cap, it's clean. returns void, takes exactly one thing, we love a function that knows what it wants 💜

🔥 DESCRIPTION 🔥

so what does it do? it's used to bring the superblock down and free the private data. that's it, that's the gig 💀

like, this is the cleanup queen. superblock goes down, private data gets freed, and nobody has to think about it again. periodt. 🧹✨

bestie heads up — "bring the superblock down" is the wording the page gives us, so don't come for me with follow-up questions, i'm just the messenger 🙈
