dmem_cgroup_uncharge(9)

💅 NAME

okay bestie, welcome to dmem_cgroup_uncharge(9) from the Kernel API Manual ✨. This one is literally all about how you uncharge a pool 🫶.

✨ SYNOPSIS ✨

void dmem_cgroup_uncharge (struct dmem_cgroup_pool_state *pool , u64
       size );

🎀 ARGUMENTS 🎀

• pool — the pool you're uncharging, bestie 🫧.
• size — the size you're uncharging, no cap 📏.

🦋 DESCRIPTION 🦋

So this is the undo button for dmem_cgroup_try_charge 😭👑. It undoes the effects of dmem_cgroup_try_charge.

Heads up, queen: you must call it with the returned pool as the argument, and with the same index and size. Same index, same size — keep that energy exact 💅.
