ubi_dbg_is_power_cut(9)

okay so bestie, welcome to ubi_dbg_is_power_cut(9) from the Kernel API Manual — this is the UBI debug helper that does one tiny, iconic vibe check: is it time to emulate a power cut? 💅✨

💖 NAME

ubi_dbg_is_power_cut — if it is time to emulate power cut.

✨ SYNOPSIS

The signature is literally this:

bool ubi_dbg_is_power_cut (struct ubi_device *ubi , unsigned int caller
);

🎀 ARGUMENTS

• ubi — UBI device description object.
• caller — -- undescribed -- (yes, the manual really just leaves it at that, bestie 🙈).

🦋 DESCRIPTION

Returns true if power cut should be emulated, otherwise returns false.

That's the whole plot. It's giving tiny boolean gatekeeper, no cap. 🌸
