🌸 NAME 🌸

write_mem_fence — the write memory barrier that orders only stores. that's it. that's the whole job. she's a specialist 💅

🦋 DESCRIPTION 🦋

okay so real talk: write_mem_fence is a write memory barrier, and it orders only stores. not loads, not everything — just the stores. she knows her lane and she stays in it ✨

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

• CLK_LOCAL_MEM_FENCE — the local one 🏠
• CLK_GLOBAL_MEM_FENCE — the global one 🌍

so yeah, mix and match as your heart desires 💜
