okay so nilfs_ioctl_mark_blocks_dirty does exactly what it says on the tin — it marks metadata file blocks or data blocks as dirty. no cap, that's the whole vibe check. 💅

⭐ RETURN ⭐

On success you get back the number of processed block descriptors (slay, it tells you how many it handled). On failure you get one of these negative error codes, and it's giving sad girl hours 😭:

  • -EIO — I/O error 🔥
  • -ENOENT — non-existent block (that's a hole block, literally not there 🙈)
  • -ENOMEM — not enough memory available, the struggle 💀
