clear_mapped_location(9)

💖 clear_mapped_location(9) — a Kernel API Manual glow-up, bestie ✨

okay so this is the clear_mapped_location(9) page from the Kernel API Manual, and we're gonna get through it together. no cap. 🫶

🌸 NAME 🌸

clear_mapped_location — clears a data_vio's mapped block location, setting it to be unmapped. literally that's the whole name section, slay. 💅

✨ SYNOPSIS ✨

void clear_mapped_location (struct data_vio *data_vio );

🎀 ARGUMENTS 🎀

• data_vio — the data vio. that's the argument, bestie. 🦋

💜 DESCRIPTION 💜

so the way this goes: this indicates the block map entry for the logical block is either unmapped or corrupted. it's giving "that mapping is not okay" energy, fr fr. 😭

🔥 SEE ALSO 🔥

okay bestie, this list is long and I am not skipping a single one. every reference stays exactly as it is. 👑
