fscache_relinquish_volume(9)

okay bestie, this is the fscache_relinquish_volume(9) page from the Kernel API Manual, and it's literally the “we're done with this volume's caching era” moment 💅✨

🎀 NAME 🎀

fscache_relinquish_volume — Cease caching a volume 🛑

✨ SYNOPSIS ✨

void fscache_relinquish_volume (struct fscache_volume *volume , const
       void *coherency_data , bool invalidate );

💅 ARGUMENTS 💅

• volume — the volume cookie 🍪 iconic, essential, no notes
• coherency_data — a piece of arbitrary coherency data to set (or NULL) 📝
• invalidate — true if the volume should be invalidated 💀

🌸 DESCRIPTION 🌸

Indicate that a filesystem no longer desires caching services for a volume. It's giving closure, fr fr 🦋

⚠️ bestie, the caller must have relinquished all file cookies prior to calling this. All of them. No cap. 🙈

The stored coherency data is updated. That's the little glow-up ✨
