So like. read_mem_fence is a read memory barrier that orders only loads. That's the whole job. Loads. Only. It's giving focused, it's giving main character energy 👑

The flags argument tells you which memory address space we're talking about, and it can be set to a combination of these literal values:

• CLK_LOCAL_MEM_FENCE
• CLK_GLOBAL_MEM_FENCE
