set_mapped_location(9)

🌸 NAME — set_mapped_location(9) 🌸

okay bestie, welcome to the Kernel API Manual page for set_mapped_location(9) 💖. This one decodes and validates a block map entry, then sets the mapped location of a data_vio. It’s giving “block map entry gets decoded, validated, and assigned,” no cap ✨.

✨ SYNOPSIS ✨

int set_mapped_location (struct data_vio *data_vio , const struct
block_map_entry *entry );

💅 ARGUMENTS 💅

• data_vio — the data vio 🫶, literally the data vio in question.
• entry — the new mapped entry to set ✨, the new mapped entry getting set.

🔥 RETURN 🔥

The return vibe is VDO_SUCCESS or VDO_BAD_MAPPING if the map entry is invalid, or an error code for any other failure. So yeah, invalid map entry gets the red flag 🚩, and any other failure brings its own error code.
