🎀 SYNOPSIS 🎀

unsigned int ata_read_log_page (struct ata_device *dev , u8 log , u8
       page , void *buf , unsigned int sectors );

like, that's the whole signature. she's giving function prototype realness 🫶

  • log — the log to read 📖
  • page — the page to read 🔖

  • sectors — how many sectors to read 🔢

💖 DESCRIPTION 💖
