💅 dm_test_psr_..._and_allowed — the manual page, bestie edition 💅

okay so picture this: you're poking around the Kernel API Manual (that's the man page section, and the page itself is literally called dm_test_psr_..._and_allowed(9) — yes the name is that long, she's extra and we love her for it) 🎀

✨ NAME ✨

dm_test_psr_is_active_allowed_requires_enabled_and_allowed — bestie, the whole entire point of this one is that both link flags have to be set before PSR active is allowed. That's it, that's the thesis. No shortcuts, no vibes-based loopholes. 🫶

🌸 SYNOPSIS 🌸

🦋 ARGUMENTS 🦋
