💅 drm_pagemap_page_set_flags(9) — like, the Kernel API Manual one 🎀

okay bestie, so this is a lil page from the Kernel API Manual, and it's all about drm_pagemap_page_set_flags — yes that's a long name, she's got main character energy, we respect it 💖

✨ NAME ✨

drm_pagemap_page_set_flags — sets flags on a device-private folio 🦋

🌸 SYNOPSIS 🌸

void drm_pagemap_page_set_flags (struct page *page , unsigned long flags );

🎀 ARGUMENTS 🎀

• page — a pointer to a page of the device-private folio. literally just the page, bestie 🙈
• flags — the DRM_PAGEMAP_ZDD_FLAG_* bits you wanna set ✨

⭐ DESCRIPTION ⭐

So what does it actually do? It preserves any flags that are already encoded alongside the ZDD pointer 🫶. That's it, that's the whole vibe. Nothing gets clobbered, no cap 💅

ngl this one is short and sweet — the way that a function can just do one thing and do it well is so iconic of it honestly 👑
